EUVE SPACECRAFT AND INSTRUMENTS CONTINUE TO OPERATE FLAWLESSLY
--------------------------------------------------------------
FIRST EUVE TARGET OF OPPORTUNITY OBSERVED
------------------------------------------
The EUVE observatory continues to operate flawlessly. GO targets
observed since the last newsletter include Jupiter, Delta Cen,
HD 131156, PG1159, MU Cen, Mk 478, NGC 5548 and Eta Cen. EUVE
also observed its first Target of Opportunity with a coordinated
observation of the moon during the last Shuttle Flight. Astronomers
interested in possible target of opportunity observations should
phone the EUVE ESOC at 1-510-643-7087. TOO approvals will
be coordinated with the project scientists Dr Yoji Kondo.

The first EUVE GOs to receive their EUVE data have visited
the EUVE GO Support Group at CEA.

EUVE BRIGHT SOURCE LIST VERSION 3 RELEASED INTERNALLY AT UCB
------------------------------------------------------------
B Stroozas and the EUVE data analysis support group have released
version 3 of the EUVE Bright Source list internally to the EUVE
project. Version 3 now contains 456 sources. Of these some 242
have possible optical counterparts identified; 110 of these are late type
stars, 80 are hot white dwarfs, 9 are cataclysmic variables,
4 A star systems, 5 BL Lac objects, 2 AGN, 3 B stars, 2 central
stars of planetary nebulae, 1 low mass x ray binary and 1 pulsar. 25
are of undetermined spectal type.

The Bright Source list is currently being scrubbed for public
release with the NASA EUVE NRA and on the EUVE public archive.
This release is currently expected to occur before the end of May.
The EUVE Bright source list will also be distributed at the EUVE booth
at the AAS meeting in Berkeley, California.

EUVE GO NRA EXPECTED TO BE RELEASED IN MAY
------------------------------------------
As planned NASA plans to release the EUVE NRA
for the second round of the EUVE GO program in May. Proposals
will be due to NASA in August.

EUVE SPECTROSCOPIC DATA TO BE RELEASED PUBLICALLY
-----------------------------------------------------
The EUVE project will soon release publically the EUVE
calibration spectra . These spectra will provide
potential EUVE GOs with reference spectra to assist them.
In addition the data on the target AU MIC will also be
released; there are no approved GOs for the AU MIC data, hence
it will be deposited in the EUVE public archive. Exact dates
for the release of data will be announced at least two weeks
before the data is made public. Exact dates for the NASA NRA
and the public release of calibration spectra will be given in the
next EUVE electronic news. Watch this space !

EUVE RESULTS TO BE PRESENTED AT AAS MEETING IN JUNE
--------------------------------------------------

Early results from EUVE will be presented at the AAS meeting in
June being held in Berkeley, California. Titles of some
of the papers are listed here. To contact the lead author of
