Internal Release of first EUVE bright source list
The first official list of bright EUVE sources was released
internally to the EUVE project at UCB. This list covers the first
16 days of the sky survey. The list was compiled from 163
sources detected using the "code B" detection algorithm ;
the data from each detected source was examined visually 
to screen out spurious or posibly spurious sources.  This
was achieved by convolving the images with the point spread
function observed from the very bright EUV source Feige 24 and
eliminating sources of suspect morphology or significance.

This screening resulted in a final list of 49 definite sources
and an additional 59 sources which are being analysed further.

The 49 definite sources have been compiled into the first EUVE
bright source list. Classes of sources in this first list include
hot white dwarfs, planetary nebula, RsCVns, flare stars, cool
star coronae, solar analogs and B stars. Of the list of 49, 20 sources
had no immediate optical counterparts and have been handed
over to the optical identification subgroup for optical identification.

A careful comparison with the ROSAT WFC bright source list
indicates that for the same sky area at low ecliptic latitude (<60deg)
the EUVE bright source list had 28 definite sources, ROSAT WFC
reported 10 bright sources of which 7 were detected by EUVE.

Prox Cen Flare observed by EUVE: a very small flare
Dr Peter Vedder reported to the EUVE science team that
an EUV flare was recently detected on Prox Cen. The
maximum flare intensity was approx 10(27) ergs/sec; this
flare was well detected and is of particular interest
because of its low intensity which compares with the
energetic of solar flares and will permit direct
solar flare comparisons.  For Further information contact

EUVE monitors flare on CV VW Hyi during outburst
By serendipity EUVE monitored the cataclysmic variable
VW Hyi during its recent "normal" outburst . The outburst
was monitored for EUVE by the AAVSO. Analysis of
the EUV data is underway. For futher information contact

Erratum: UZ For
In the previous newsletter the EUVE detection of the
Cataclysmic Variable UZ For was reported. We noted
that UZ For was not detected by the ROSAT WFC - we
have been informed that the reason that UZ For was
not in the ROSAT Bright source list was that it is
located  in a gap of sky not covered by ROSAT WFC for
the ROSAT WFC Bright Source List. The EUVE detection
is still firm.
