1.1 Recent EUVE Science Highlights
----------------------------------
by Dr. Pierre Chayer, EUVE/CEA Scientist
EUVE OBSERVATIONS OF THE QUIESCENT AND FLARING CORONA
OF THE FLARE STAR AU MICROSCOPI
Drs. B.C. Monsignori Fossi, M. Landini, and G. Del Zanna from the
Dipartimento di Astronomia e Scienza dello Spazio at the Universita di
Firenze in Italy, and Dr. S. Bowyer from CEA, observed and analyzed
the EUVE spectrum of AU Mic. AU Mic is a flaring and rapidly rotating
M2 Ve star at a distance of 8.8 pc. EUVE detected AU Mic both in the
scanning mode and with the Deep Survey/Spectrometer, which is equipped
with a direct broadband imaging detector and three spectrometers to
cover the short (70-190 A, SW), medium (140-380 A, MW), and long
(280-760 A, LW) extreme-ultraviolet wavelengths. These instruments
allow simultaneous imaging and spectroscopy with a spectral resolution
of 0.5, 1, and 2 A in the SW, MW, and LW detectors, respectively.
Two flares were detected in the course of the observation of AU
Mic. A first large flare was detected in all three spectrometer
channels, followed by a decaying phase. A second, smaller flare was
observed in the SW and MW channels. The large flare peaked very
quickly, while the descending phase lasted about three hours. The star
remained active between the two flares and returned to the quiescent
level only after the second flare.
The EUVE spectrometers allow individual line identifications and
detailed spectroscopic analysis. In the AU Mic observation, several
highly ionized iron lines were well detected (Fe XV, XVI, XVIII, XIX,
XX, XXI, XXII, XXIII, XXIV). These lines were used to characterize
the temperature region logT = 5.8 - 7.3 and to provide the
differential emission measure (DEM).
Dr. Monsignori Fossi and her colleagues also performed an analysis
of the DEM as a function of time. They found that a high-temperature
component is present in the flaring and decay phases of the flares
that shifts toward higher temperatures at the flare peaks. The
enhancement of this hot component may be easily followed during this
time and is responsible for most of the flare brightening.
Finally, using the Fe XXI 142.2 A blend spectral line,
Dr. Monsignori Fossi's group showed that both the line ratios and the
synthetic spectrum computed during quiet and flaring conditions
suggest an increase of electron density during flares, ranging between
3.0E+12 and 2.0E+13 cm^(-3). The densities obtained for the AU Mic
flares are more than an order of magnitude larger than the values
found in solar flares.
NOTE: The EUVE science team are deeply saddened by the loss of
their colleague and friend, Brunella Monsignori Fossi, who
died unexpectedly on 22 January 1996.

THE EUV SPECTRUM OF THE QUASI-COHERENT OSCILLATIONS OF THE DWARF NOVA
SS CYGNI
C.W. Mauche
To appear in Astrophysical Journal.
Data obtained by the Extreme Ultraviolet Explorer satellite are
used to determine the EUV spectrum of the quasi-coherent oscillations
of the dwarf nova SS Cygni. It is found that the spectrum of the
oscillations is neither blue nor red nor grey relative to the net
(oscillation-phase integrated) spectrum, and hence that the
oscillations cannot be explained by variations in the effective
temperature, absorbing column density, or effective area,
respectively. Instead, it is found that the amplitude of the
oscillations is high at the relative maxima of the net spectrum, and
low to zero at the relative minima of the net spectrum. This behavior
can be explained by either variations in the emission line flux atop a
constant underlying continuum, or variations in the optical depth of a
haze of overlapping absorption lines, in which case the optical depths
must be tau < 1 at the relative maxima of the net spectrum, and tau >>
1 at the relative minima.

A CHEMICAL METHOD TO INCREASE EXTREME ULTRAVIOLET MICROCHANNEL PLATE
QUANTUM EFFICIENCY
R. Hemphill, J. Edelstein, and D. Rogers
To appear in Applied Optics. [CEA publication #755]
The quantum detection efficiency (QDE) of photon counting
microchannel plate detector channels can be increased by a factor of
two in the extreme ultraviolet bandpass, from 256 A to 1024 A, by
subjecting the input channel plate to a chemical solution treatment.
The efficiency increase has proven insensitive to the exposure of
laboratory atmosphere and is stable over the extracted charge lifetime
equivalent of multi-year astrophysical observations. Chemically
treated microchannel plates that are overcoated with opaque
photocathodes of KBr and CsI show a factor of two QDE increase from
834 A to 1100 A in comparison with previous measurements using
conventional untreated microchannel plates.
--------------------------------------------------------------
AN ALL-SKY CATALOG OF FAINT EUV SOURCES
M. Lampton, R. Lieu, J.H.M.M. Schmitt, S. Bowyer, W. Voges, J. Lewis,
and X. Wu
To appear in Astrophysical Journal Supplement. [CEA publication #756]
We present a list of 534 objects detected jointly in the Extreme
Ultraviolet Explorer (EUVE) 100 A all-sky survey and in the ROSAT
X-Ray Telescope 0.25 keV band. The joint selection criterion permits
use of a low count rate threshold in each survey. This low threshold
is roughly 60% of the threshold used in the previous EUVE all-sky
surveys, and 166 of the objects listed here are new EUV sources,
appearing in neither the Second EUVE Source Catalog nor the ROSAT Wide
Field Camera Second Catalog. The spatial distribution of this all-sky
catalog shows three features: an enhanced concentration of objects in
Ursa Major, where the Galactic integrated HI column reaches its global
minimum; an enhanced concentration in the third quadrant of the Galaxy
(l_II from 180 deg to 270 deg) including the Canis Major tunnel where
particularly low HI columns are found to distances beyond 200 pc; and
a particularly low number of faint objects in the direction of the
fourth quadrant of the Galaxy, where nearby intervening HI columns are
appreciable. Of particular interest is the composition of the 166
detections not previously reported in any EUV catalog. We offer
preliminary identifications for 105 of these sources. By far the most
numerous (81) of the identifications are late-type stars (F,G,K,M),
while 18 are other stellar types, only 5 are white dwarfs (WDs), and
none is extragalactic. The paucity of WDs and extragalactic objects
may be explained by a strong horizon effect wherein interstellar
absorption strongly limits the effective new-source search volume and,
thereby, selectively favors low-luminosity nearby sources over more
luminous but distant objects.
--------------------------------------------------------------
THE EXTREME ULTRAVIOLET SPECTRUM OF THE BL LACERTAE OBJECT MRK 421
J.F. Kartje, A. Konigl, C.-Y. Hwang, and S. Bowyer
To appear in Astrophysical Journal. [CEA publication #757]
We carried out a spectroscopic observation of the BL Lacertae
object Mrk 421 with the Extreme Ultraviolet Explorer satellite over a
11-day period in late April/early May 1995 (~242 ksec useful time).
During this period the source underwent a flare that was detected also
in X-rays and TeV gamma-rays. The best continuous coverage of the
flare was obtained by EUVE, which resolved the smooth rise and fall of
the flux, measuring the variability of as much as a factor of ~1.5
over a span of ~2 days. The detected spectrum extended from ~65-100 A
and could be fit with a power law of energy spectral index alpha_EUV
~= 3.5 +/- 0.8 for the measured Galactic hydrogen column density. The
EUV spectrum is much steeper than the mean 1.5 - 5.0 keV X-ray
spectrum, alpha_X = 1.63 +/- 0.02, measure simultaneously by the ASCA
satellite. Furthermore, a simple power-law fit to the observed fluxes
at 85 A and 1.5 keV (excluding the data from the first 3 days, the
time of maximum variability) significantly overestimates the flux at
the shortest detected EUV wavelengths. These two findings imply that
strong absorption is occurring between ~65 and ~75 A. Such absorption
is quite similar to that detected previously in our observation of the
BL Lacertae object PKS 2155-304. We demonstrate that this absorption
can be attributed to a superposition of Doppler-smeared absorption
lines originating in high-velocity, QSO-type nuclear clouds of total
column density ~5E+21 cm^(-2) that are ionized by the beamed continuum
of the associated relativistic jet. We identify the lines as mostly
L- and M-shell transitions of Mg and Ne. The data suggest that the
velocity range spanned by the clouds is relatively small (from v_i ~=
0.05c to f_v ~= 0.1c). We find that such a range is consistent with a
scenario in which the clouds are initially accelerated to v_i by a
magnetized outflow from a nuclear accretion disk, with radiation
pressure further accelerating them to V-f after they enter the beamed
emission cone of the jet. We also compute the expected cloud
absorption lines in the UV and soft X-ray regimes and use these
results to constrain the clouds' physical parameters and chemical
composition.

2. EUVE Science Operations News
===============================
2.1 EUVE Outsourced Extended Mission Status Report
--------------------------------------------------
by Brett Stroozas, EUVE Science Operations Manager
Since the launch of EUVE in Jun 1992, CEA has been the operations
center for the command and control of the EUVE science payload. The
payload is mounted on the Explorer Platform spacecraft (EP), which has
been operated since launch by a Lockheed-Martin (L-M) Flight
Operations Team (FOT) under the management of GSFC.
In Apr 1996 CEA submitted an unsolicited proposal to NASA for an
EUVE outsourced extended mission (OEM) in which CEA would take over
from GSFC the management of EP operations. The OEM plan was for CEA
to team with an industrial partner (IP; e.g., L-M) who would then
perform the actual daily EP operations, with CEA performing the
overall project operations management. The idea behind this proposal
was that CEA would manage/operate the entire satellite at an overall
lower cost by streamlining EP operations (similarly to what CEA has
done for the payload), by providing integrated payload and EP
operations management, and by reducing the reliance on NASA
institutional support elements (e.g., the Packet Processor and Flight
Dynamics Facilities). This OEM plan outlined a scheduled
management/operations hand-over to occur in early 1997.
CEA's proposal was approved by NASA in May 1996. In Apr CEA
released a Request for Proposals (RFP) calling on all potential IPs to
bid for the EUVE OEM operations contract under CEA management. The
RFP called for the IP to perform two major functions: (1) to operate
the EP on a daily basis, and (2) to set up the EP command and control
center; all of this was to be done under a firm, fixed-priced (FFP)
contract. A handful of companies expressed initial interest in
bidding and attended a bidder's conference held at CEA in late Apr;
unfortunately, when the proposal acceptance period closed in late May
CEA had received no bids. In follow-up discussions with some of the
applicable companies the major reasons given for not bidding were
working under a FFP contract and the perceived high risk of not making
a large enough profit margin given the work to be performed. So,
based on the null result of the RFP, CEA put into effect its backup
plan: CEA would do it all -- manage and operate the EP -- from an EP
Operations Center (EPOC) to be set up at and by CEA.
Based on the results of the RFP process, NASA revised the OEM plan
into the following two phases:
o Phase 1, Operations Management -- CEA will take over from GSFC the
EP management and operations in mid-Feb 1997. Until that time,
GSFC will extend the operations contract of the incumbent L-M FOT.
Under this contract extension the L-M FOT will be additionally
tasked with providing EP operations training to the newly-hired CEA
FOT personnel.
o Phase 2, Science Management -- Upon completion of Phase 1, CEA will
take over from GSFC all EUVE science management activities (e.g.,
management of the Guest Observer Program). During the Phase 1
work, transfer of the science management activities will commence
and be incrementally phased in.
Although the details of the Phase 2 transition are still under
discussion with NASA, the following are some of the major
accomplishments to date for Phase 1:
o In Jun CEA sent a draft of its OEM implementation plan to GSFC for
review. A "working group" telecon was held between GSFC and CEA on
27 Jun in order to review and comment on this plan. A number of
Review Item Discrepancies (RIDs) were generated that require
follow-up actions and/or clarifications to the plan; work on
revising the OEM implementation plan based on these RIDs is in
progress.
o A Cooperative Agreement between NASA GSFC and CEA has been signed
off, making the OEM official.
o CEA has chosen to use the Transportable Payload Operations Control
Center (TPOCC) as the basis for EP operations in the CEA EPOC.
TPOCC is a workstation-based command and control system that has,
for the past few years, been under development at and by GSFC for
EUVE; EUVE TPOCC is scheduled for final delivery in mid-Oct 1996.
In lieu of TPOCC CEA had been seriously considering going with a
commercial command and control system (in particular, CEA had been
focusing on the possible use of a system called EPOCH 2000 from
Integral Systems, Inc.). However, the use of TPOCC was chosen over
that of a commercial system due to a combination of cost, schedule,
and risk considerations.
o The development of the EPOC at CEA is in full swing. The EPOC
systems, which will leverage heavily off of those currently (or
soon to be) in operations for EUVE at GSFC, will be supplied to CEA
as government-furnished equipment (GFE). Initial shipments of GFE
from CEA have included a spare package of the Command Management
System (CMS) hardware and software, the EP Planning System (EPPS)
software, and the current release of the TPOCC software.
o Hiring and staffing of the EPOC FOT is in progress and will be
completed soon. The newly-hired FOT staff will then be sent to
GSFC for ~2 months of training with the incumbent L-M FOT.
Some of the major upcoming Phase 1 schedule milestones include the
following:
o Complete EPOC FOT Hiring/Staffing 09/02/96
o EPOC FOT Training at GSFC 09/16/96 - 11/22/96
o GSFC OEM Review ~11/96 (tentative)
o Complete EPOC Development 12/01/96
o Begin Shadow Operations Period 01/06/97
o Complete Operations Hand-over 02/15/97
As noted above, a full-up detailed review of CEA's OEM implementation
plan/progress will probably occur sometime in the late-Oct or
early-Nov timeframe (exact date TBD). This review will ensure that
all of the relevant major issues have been properly addressed, and
that the overall implementation is progressing according to the
planned schedule. A "shadow operations" period is slated for Jan/Feb
1997, in which CEA will progressively take on more and more of the
daily EP operational responsibilities. A final operations hand-over
from GSFC to CEA is scheduled to occur in mid-Feb 1997, at which point
the outsourcing will be complete.
2.2 Public GO/RAP Data Release for 1 Sep 1996
---------------------------------------------
by Dr. Nahide Craig, EUVE User Support Scientist
The table below lists the GO/RAP observations that become public on
1 Sep 1996. For each observation is given the target name, the
approximate exposure time in ksec, the GMT start/end dates, the
target's spectral type, and the data identification code (GO and RAP
data are marked accordingly). All public data sets can be ordered
from the archive via WWW and electronic or postal mail (see addresses
below). Please be sure to include in your order the DataID(s) of
interest. Processed data sets are shipped via postal mail on 8mm tape
or (if requested) on CD-ROM.
The data rights policies for observations state that Principal
Investigators (PIs) have proprietary rights to the data for a given
period of time from the date (s)he receives it. It is often the case
that long observations are broken up over many months; e.g., an
observation approved for 60 ksec may actually be observed for 10 ksec
one month, 20 ksec the next, and 30 ksec three months later. In such
cases the proprietary period begins after the PI is sent the final
piece of the completed observation.

3. Science Education News
=========================
by Dr. Isabel Hawkins, CEA Science Education Director
3.1 Science Information Infrastructure Project
----------------------------------------------
Year two of this exciting project is underway. The San Francisco
Exploratorium, the Berkeley Lawrence Hall of Science, and the National
Air and Space Museum will continue to develop and pilot-test their
classroom modules with their teachers, while Science Museum of
Virginia will be pilot-testing the activities independently to ensure
that they can be used in a variety of classroom situations. The
Exploratorium's "Aurorae -- Paintings in the Sky" lesson plan (URL:
http://www.exploratorium.edu/learning_studio/sii) has been selected by
PacBell for their on-line "Bluewebn" award.
3.2 Interactive University Project
----------------------------------
CEA is a member of the UCB campus-wide coalition "The Interactive
University" for the purpose of carrying out effective outreach to the
community. The Interactive University Project has become the
technology arm of the "Berkeley Pledge" which is the UCB Chancellor's
official outreach program to the neighboring school districts. As
part of this coalition, CEA has partnered with the Oakland and San
Francisco School Districts in Technology Challenge Grants submitted to
the U.S. Department of Education. These grants would be used to
develop an articulated program for all grade levels that will
successfully integrate technology into the Districts' math and science
curricula. As part of the Berkeley Pledge CEA has received funding
for three years beginning in October 1996. The CEA's contribution to
the collaboration will be the Science On-Line Program methodology,
which will be adopted by the two school districts to carry out their
teacher professional development program for science. An important
component of this effort will include the design and implementation of
a feasible methodology for the participation and contribution of
scientists to education.
3.3 Astro-QUERY Project
-----------------------
Science Education activities at CEA will continue to rely on the
Internet as their primary publishing tool, and its use will be
facilitated by the development of an innovative information server
based on hypertext markup language (HTML) forms -- a familiar
interface to World Wide Web users. The Astro-QUERY CEA Information
Server will give users the ability to retrieve information on the EUVE
satellite mission and data archive that is tailored to their level of
expertise. Astro-QUERY, being developed for the Science Education
Program, will allow the user to specify parameters that indicate the
desired levels of complexity, breadth, scope, format (e.g., text or
graphics), etc. of the requested information topic. The K-12 education
materials for the Astro-QUERY Information Server are being developed
at CEA via a teacher intern program. Dr. Nellie Levine, a physics
teacher from Galilleo High School in San Francisco, created outlines
for the following two tutorials, which will access a variety of
relevant resources from the EUVE mission and data:
o "Be an Engineer -- Learn How to Operate a Satellite"
o "Be a Scientist -- Learn How to Become a Space Researcher"
Dr. Levine and two of her high school students are spending one month
this summer at CEA, funded by a planning grant obtained from the UC
Office of the President. To support full implementation of this
project, CEA is submitting to the Corporation of Public Broadcasting a
proposal that includes the new San Francisco Public Library. A paper
describing this project has been submitted to the American Education
Research Association.
3.4 Advisory Board Meeting
--------------------------
The next science education advisory board meeting will take place
at CEA on 19 August 1996. CEA is looking forward to sharing its
progress with its colleagues.
