EUVE CONTINUES SKY SURVEY 
-------------------------
The EUVE observatory is now in the second week of the sky survey.
All instruments and the spacecraft continue to operate nominally.
EUV sources are being detected on a regular basis.

The initial processing of the first week of sky survey  data  re-
vealed  a  timing  offset  between the telemetry and the attitude
solution, resulting in source positions with a systematic  offset
of  a  tenth  of  a  degree.  This has now been corrected and the
first week is being reprocessed.

The first new EUV sources have now been detected in the sky  sur-
vey  data.   One of the new deep survey sources is located in the
same field of view as a previously reported ROSAT WFC source. The
new  source  is  of  similar  intensity  as the ROSAT WFC source.
Several of the EUV sources observed so far have proved to be dou-
ble.

Count rates observed by EUVE appear to  be  significantly  higher
than  the  reported  count  rates  from  the  ROSAT  WFC for many
sources. This is not fully understood at this time.

The moon was imaged in the sky survey  detectors,  including  the
long  wavelength  scanner. The count rates are considerably lower
than the modeled predictions. As a result  the  moon  will  cause
less contamination than feared, and will not result in high count
rate shutoff of the detectors.  The moon was  also  used  to  map
residual  stray  light and leaks out of field of view. There were
no surprises.

Calibration data from AU  Mic  are  being  analyzed.  The  source
flared  strongly  twice  during  the  calibrations. Many spectral
lines were detected in both the short and long  wavelength  spec-
trometers  so  that wavelength calibration will be possible using
this data.

AR Lac and II Peg were both well observed during the calibrations
and the data are being analyzed.

At the Friday science team meeting there was much  discussion  of
the  very  low backgrounds seen in the detectors and implications
for models of emission  from  the  interstellar  medium.  Initial
analysis of the scanning spectrometer data by Vallerga and Jelin-
sky are encouraging also and indicate that the  spectrum  of  the
background  obtained during the sky survey will be scientifically
very interesting.


EUVE BIBLIOGRAPHY AVAILABLE
---------------------------
The complete bibliography of EUVE papers from the Center for  EUV
Astrophysics  is  now  available from the Public Archive via ftp.
The file EUVE_bib is a listing, in troff format, of all the  EUVE
papers, categorized by subject.

To request one or more papers, e-mail editorial@cea.berkeley.edu,
giving  your postal address and the number(s) of the paper(s) you
want from the list.
