PUBLIC RELEASE OF EUVE CALIBRATION DATA
From: Ron Oliversen, EUVE Deputy Project Scientist, NASA-GSFC
*******************************************************************
A release of calibration data taken during In-Orbit-Checkout and
the Survey phase of the mission will be available through the EUVE
public archive on June 14.  This release will be 1-d spectra (counts
vs. wavelength) as processed with EGO software version (1.1.1).  Some
calibration data were processed with more recent versions, and a 
README file is included with each spectrum to indicate the appropriate
software version. Included in this release, but available earlier on
(1 June), are the 1-d spectra of AU Mic in a quiescent and flare phase.
Also, the raw data set of AT Mic and EGO reduction software version
(1.1.1) will be released on June 7. AT Mic data and EGO software will
be available on CD ROM at the AAS meeting or by accessing the files
through the CEA ftp site.  These spectra are being released WITHOUT
restrictions on their use.  However, caution is advised against
over-interpretation and questions about the data reduction should be
directed to (egoinfo@cea.berkeley.edu).  Also, the updated tables of
significantly improved telescope effective areas as a function of
wavelength are available through the public archive.

(The calibration targets that will be released are:
WD 1845, WD 2309, Procyon, WD 1620, MCT 2020, PKS 2155, HR 1099
Feige 24, Capella, WD 0549, G191 B2B)

EUVE SCIENCE ARCHIVE RELEASES FIRST CD ROM AT JUNE AAS
From: Jeremy Drake
******************************************************
Less than one year after launch, the EUVE Science Archive is pleased
to announce the impending release of Volume 1 Number 1 in what will
be a series of CD ROMs containing EUVE mission data and software.
The release coincides with the June 1993 AAS meeting, to be held at
UC Berkeley. If you plan to attend the AAS meeting, you may obtain a
copy of the CD at the EUVE stands.  Details of how to request a copy 
to be sent by mail to AAS non-attendees will be announced in a future
Newsletter.  Please do not request a copy at this time.

CD ROM CONTENTS
---------------
The CD ROM contents include selected data from the first 7 months of
operation of the Extreme Ultraviolet Explorer Satellite, software for
reduction and analysis of data obtained in the EUVE Guest Observer
(EGO) program, and miscellaneous pertinent data and software.

AT MIC COMPLETE DATA SET
------------------------
AT Mic was observed as a spectrometer calibration target in July 1992.
The complete AT Mic data set from this observation is being made
available on EUVE CD ROM Vol. 1 No. 1.  This data represents a sample
of the nominal EUVE Guest Observer Center (EGOC) processing of an
observation, and is similar to what is provided to each EUVE Guest
Observer for their observations.  
The data is presented as 1-D FITS files containing the extracted
spectra, 2-D wavelength corrected FITS images, various telemetry and
engineering tables, and QPOE files containing photon position and time
information in binary tar format.  Data reduction software, a
reference data set, and documents relating to the guest observer
software are also provided.
This data set will also be release simultaneously through anonymous
ftp to the Science Archive site (ftp.cea.berkeley.edu).

EUVE BRIGHT SOURCE LIST
----------------------
Version 2a of the EUVE Bright Source list is recored on the CD in
LaTeX, PostScript, and ASCII formats.  This version forms a subset of
those sources to appear in the actual BSL to be published with the
NASA Research Announcement.  It contains information on all verified
survey sources from both the long-exposure (``deep'') survey of the
ecliptic and the all-sky survey, together with possible optical
counterparts found from a search of existing astronomical catalogues.


OTHER CONTENTS
In addition to the above, the CD also contains a compilation of
miscellaneous mission-related documents, images of extended sources
detected in the all-sky survey, images of the EUVE skymaps in four
bandpasses, C software to calculate the interstellar medium
transmission at EUVE wavelengths, and the complete collection of
publicly released EUVE calibration spectra.

EUV ASTRONOMY FEATURED AT AAS - INVITATION TO CEA RECEPTION
***********************************************************
The session on EUV Astronomy at the American Astronomical
Society meeting is being held on Tuesday June 8 from
8:30 to 5:30 pm. Latest results from EUVE, ROSAT WFC,
HUT, Voyager and theoretical discussions will be
presented. The evening poster session from 6-8pm will
be held at the Center For EUV Astrophysics at Berkeley.
A reception with no host bar will be held Tuesday
evening at CEA during the poster session. Details in
AAS registration packets.
