Notes from the Editor
=====================
by Brett A. Stroozas, Data Analysis Support Staff (DASS)
and Archive Manager
Welcome to the electronic newsletter for NASA's Extreme Ultraviolet Explorer
satellite (EUVE), which is compiled and published monthly by the EUVE Public
Science Archive group at the Center for EUV Astrophysics (CEA) in Berkeley,
CA. As mentioned in the previous issue (v4.4, 12 April 1994), EUVE suffered
its first major hardware failure with the loss of its "B" side transmitter on
2 April. The Flight Operations Team at Goddard Space Flight Center (GSFC)
quickly switched to the "A" side, insuring no loss of science data. Except
for this incident, which continues to be investigated, the EUVE observatory
performed well throughout the month of April, completing observations of the
following Guest Observer (GO) targets: MRK 421 (BL Lac), LB 1919 (WD), and
MRK 279 (AGN).
The contents of this issue of the EUVE electronic newsletter are as follows:

1. Notes on the Upcoming AAS Meeting
====================================
1.1 EUVE User's Committee Meeting at AAS
----------------------------------------
A special EUVE User's Committee meeting will be held at the 184th meeting
of the American Astronomical Society (AAS) in Minneapolis, MN during the week
of 29 May - 2 June 1994. The User's Committee meeting is scheduled for the
lunch break on Tuesday, 31 May in Directors Row 3. Planned topics of
discussion are a current update on EUVE and the ongoing efforts to extend the
EUVE mission. Dr. Harry Shipman, chairman of the User's Committee, is the
coordinator of this meeting and will announce further information in the near
future. The interest and input of the user community is extremely important
to the future of EUVE and we strongly encourage everyone to attend.
PLEASE NOTE: The meeting room is *incorrectly* noted in the final schedule
as Directors Row 1. The correct location for this meeting is Directors Row 3
as mentioned above.

============================================
2.1 GO Program NRA Schedule Update
----------------------------------
by Anne Miller, EGO Center Technical Writer
The dates for release of the next EUVE NASA Research Announcement (NRA),
and the projected deadline for proposal submission, have been revised to avoid
conflict with the schedules for other NRAs. The new dates are:
NRA release: 15 Jun 1994
Proposal due date: 16 Sep 1994
Peer Review: Nov 1994
Start of observations: Feb 1995
These dates supersede those published in the last issue of this newsletter
(v4.4, 12 April 1994). They remain *tentative*, and are subject to change.
2.2 Cycle II Dithered Target List
---------------------------------
by Eric Olson, EGO Support Manager
It has been known for some time that the EUVE spectrometer detectors exhibit
a characteristic fixed-pattern-noise (FPN) that results when the locations of
photon events near the boundaries of "bundles" of micro-channel fibers in the
EUVE micro-channel plate detectors are shifted. Because EUVE sees so few
EUV-bright sources, the probability is very small for accumulating sufficient
events to generate a flat-field which would remove all of the variations caused
by the FPN. Recent tests, however, indicate that it is possible to alleviate
much of the FPN by pointing the spectrometer at a series of randomly chosen
locations near the target, rather than at a single RA/Dec for the entire
observation. This technique is known as "dithering". Enclosed below is the
list of Cycle II targets that are being considered for dithered observations.
For more information on FPN and the dithering technique, contact the EGO Center
(egoinfo@cea.berkeley.edu). For information on or comments regarding dithered
observations, contact Eric Olson at CEA or Dr. Ron Oliversen at GSFC.

THE EUV SPECTRUM OF AU MIC: TEMPERATURE AND DENSITY DIAGNOSTIC FROM EUVE
SPECTROMETER OBSERVATIONS
B.C. Monsignori Fossi and M. Landini
To appear in Astronomy and Astrophysics.
EXOSAT and IUE observations of the active star AU Mic are used to develop
a model of the differential emission measure distribution (DEM) versus
temperature. The signals detectable by the Extreme UltraViolet Explorer
Spectrometers are predicted. The computation indicates the presence of
several highly ionized iron lines in the EUV spectral region. These lines
are identified in the observations of AU Mic performed by the Short (70-190 A)
and Medium (140-380 A) Wavelength Spectrometers on EUVE. Using the recorded
EUVE spectra a more accurate DEM model for the transition region and corona
of the star has been evaluated and using density sensitive lines an upper
limit on the electron density has been put.

EUVE SPECTROSCOPY OF EPSILON CMA (B2 II) FROM 70 A TO 730 A
J.P. Cassinelli, D.H. Cohen, J.J. MacFarlane, J.E. Drew, A.E. Lynas-Gray,
M.G. Hoare, J.V. Vallerga, B.Y. Welsh, P.W. Vedder, I. Hubeny, and T. Lanz
To appear in The Astrophysical Journal.
We present spectra of the brightest stellar source of extreme ultraviolet
(EUV) radiation longward of 400 A, the B2 II star, Epsilon CMa. These data were
taken with the three spectrometers aboard the NASA Extreme Ultraviolet Explorer
satellite (EUVE) during the first cycle of pointed observations. We report
on our initial studies of the continuum and line spectrum of the stellar
photosphere in the 320 to 730 A region, and on the wind emission lines observed
in the 170-375 A region. This is the first EUV spectrum of an early-type star,
and thus makes Epsilon CMa the most comprehensively observed B star from the
X-ray to infrared regimes.
The radiation in both the H Lyman continuum and HeI continuum (shortward of
504 A) are found to be significantly greater than predicted by both LTE and
non-LTE model atmospheres. Since Epsilon CMa also exhibits a mid-infrared
excess, this points to the outer layers being warmer than the models indicate.
The anomalously large Lyman continuum flux, combined with the very low column
density measured in the direction towards this star implies that it is the
dominant source of hydrogen ionization of the local interstellar medium in the
immediate vicinity of the sun. All of the lines predicted to be strong from
model atmospheres are present and several wind absorption features are also
identified. We have detected emission lines from highly ionized iron, ranging
from Fe^8 to Fe^15, which arise in the X-ray producing region. The lines are
consistent with the ROSAT PSPC observations if a multi-temperature emission
model is used, and the assumption is made that there is significant absorption
beyond that of the neutral phase of the ISM. The EUV spectrum shows a strong
HeII Lyman-alpha emission at 304 A. This line cannot be formed in the upper
regions of the photosphere, but rather is due to the recombination of He++,
which is itself produced by the X-ray and EUV (lambda < 228 A) radiation
present in the outer atmosphere. The spectrum also shows strong OIII 374 A
line emission produced by the Bowen fluorescence mechanism, which has not
previously been observed in the spectra of hot stars.

INTERSTELLAR MEDIUM CONTINUUM, AUTOIONIZATION, AND LINE ABSORPTION IN THE
EXTREME ULTRAVIOLET
T. Rumph, S. Bowyer, and S. Vennes
To appear in The Astronomical Journal. [CEA Publication #584.]
We provide a new estimate of the effective absorption cross section of the
interstellar medium at extreme ultraviolet wavelengths. The cross section for
neutral helium is discussed in detail. Two spectral features of interstellar
neutral helium, the 504 A ionization edge and the autoionization resonance
feature at 206 A, are detectable with existing instrumentation. Measurements
of the autoionization feature in continuum sources will provide a direct
estimate of the intervening neutral helium column; in many cases this will be
the only method to obtain this parameter. Although continuum metal opacities
are negligible at wavelengths greater than 50 A, we find that metal line
features should be detectable in continuum sources with high signal to noise
observations. A selection of some of the most prominent lines expected is
provided.

EUVE OBSERVATIONS OF THE MOON
G. Randall Gladstone, John S. McDonald, William T. Boyd, and Stuart Bowyer
To appear in Geophysical Research Letters, 21(6), pp. 461-464, 1994. [CEA
Publication #583.]
During its all-sky survey, the Extreme Ultraviolet Explorer (EUVE) satellite
observed the Moon several times at first and last quarters, and once near the
lunar eclipse of December 10, 1992. We present here a portion of this data, in
the form of extreme-ultraviolet (EUV) images of the Moon and derived geometric
albedos. Extreme ultraviolet observations of the Moon are of considerable
interest, since it has been speculated that lunar EUV emissions may be dominated
by L- and M-shell X-ray fluorescence and may provide a useful diagnostic of
surface elemental abundances. From the EUVE photometer data we obtain average
geometric albedos of 0.15% (+/- 0.03%), 3.1% (+/- 0.3%), and 3.5% (+/- 0.3%),
over wavelength intervals of 150-240 A, 400-580 A, and 550-650 A, respectively.
An upper limit geometric albedo of 0.13% is obtained for the wavelength
interval 75-180 A. Also, using previously published ROSAT data, we estimate a
lunar geometric albedo of 0.014% (+/- 0.002%) over the wavelength interval
50-80 A. These EUV albedos (and previously published far-ultraviolet albedos)
are well fit by the scaled reflectivities of SiO_2 and Al_2O_3. Over the
wavelength ranges of the EUVE photometers, the observed brightness of the Moon
seems to be largely consistent with reflected sunlight rather than X-ray
fluorescence. Since the L- and M-shell fluorescence signal is expected to be
carried by only a small number of emission lines, however, it will require EUV
observations of higher spectral resolution to determine their exact
contribution, if any, to the lunar EUV spectrum.

A CME MODEL FOR THE 1992 JULY 15 FLARE ON AU MICROSCOPII OBSERVED BY EUVE
Scott L. Cully, George H. Fisher, Mark J. Abbott, and Oswald H.W. Siegmund
To appear in The Astrophysical Journal. [CEA Publication #581.]
The dM1e flare star AU Microscopii (AU Mic) was observed by the EUVE Deep
Survey Instrument on 1992 July 14-18. A large flare was detected in the Deep
Survey Lexan/Boron (DS Lex/B) (65-190 A) band and the SW (70-190 A) and MW
(140-380 A) spectrometers. The flare consisted of a sharp impulsive peak
lasting approximately 2 hours followed by a decaying tail lasting about a day.
We present a simple, single temperature, dynamic model for the flare decay
which is consistent with the the DS Lex/B light curve and reproduces the
strongest, high temperature spectral lines in the released EUVE spectra. In
this model, we assume the long decay time is due to an ejected, magnetically
confined, low beta plasmoid expanding self similarly in the ambient medium in
a manner reminiscent of solar coronal mass ejections. We demonstrate that the
long tail of the DS Lex/B light curve can be explained by rapid expansion,
causing the plasma to become tenuous sufficiently quickly that it avoids
catastrophic radiative cooling. From this model, we estimate the mass of the
plasmoid to be 1e20 g and the total energy of the event to be 1e36 ergs.
These values are approximately 1e4 times as large as those seen during the
largest solar CME events. We argue that the results of our model are consistent
with other measurements of stellar flare parameters. We also estimate a mass
loss rate of a few times 10-13 M_Solar yr^(-1) and discuss the role of mass
loss from dMe stars in the mass balance of the interstellar medium. We estimate
the rotational braking time scale from these events to be less than 500 million
years and suggest that CME's may be an important source of angular momentum
loss from late type stars.

4. Educational Outreach Activities at CEA
=========================================
by Dr. Isabel Hawkins, CEA Scientist
4.1 NASA Astronaut Visits Bay Area
----------------------------------
The CEA Education Outreach Program, headed by Dr. Isabel Hawkins, had the
pleasure of hosting a 1-day visit by NASA Astronaut Jeffrey A. Hoffman, the
astrophysicist who put eyeglasses on the Hubble Space Telescope (HST).
Dr. Hoffman's schedule included an informal lunch with old friends from
Harvard and MIT and a tour of CEA where he interacted with CEA scientists
and staff, obtaining a close look at EUVE data and a hands-on introduction
to Mosaic.
After a technical presentation at CEA to an audience of eighty University
of California, Berkeley, faculty and staff, Astronaut Hoffman shared his
experiences during dinner with a group of thirty teachers, high school
students, and other professional educators.
The last event of the day was a nontechnical presentation by Dr. Hoffman
entitled "THE ULTIMATE ROADSIDE REPAIR" which took place at the Lawrence Hall
of Science. This event, for an audience of 300 people, was sponsored jointly
by CEA and the Lawrence Hall of Science. During his presentation, which
included spectacular film-footage, Astronaut Hoffman gave a firsthand account
of the capture and repair of HST. During an 11-day flight of the Space Shuttle
Endeavour in December 1993, the HST was restored to full capacity through a
record-setting five space walks by Dr. Hoffman and his fellow astronauts.
After his presentation, Dr. Hoffman answered questions from the public and
signed autographs.

5.3 Status Report on EUVE Publications
--------------------------------------
As of April 1994 CEA is aware of a total of 68 EUVE publications that have
appeared in the literature. These publications are broken down in the table
below: "RJ" indicates a refereed journal and "NRJ" indicates a non-refereed
one; non-CEA indicates publications by non-CEA scientists (i.e. Guest Observers)
and CEA indicates those by CEA scientists (which includes both Guest Observer
and sky survey science).
RJ NRJ TOTAL
