EUVE SURVEY CONTINUES
---------------------

The EUVE all sky survey is continuing smoothly. Some operational
problems were encountered last weekend due to loss of contact
to the spacecract. As a result the one month calibration period
was extended. Any resulting gap in the sky survey will be filled in
during the second six month gap filling period.

The "detection" software taste test is runnign smoothly. All
four independent detection schemes have been used to generate
source lists on the first 22 days of the survey. The results
are being intercompared. Optical identification of the
new sources is proceeding.

PKS 2155
--------

Herman Marshall presented new results on PKS 2155 to the
science team. The lack of observed variability is very
unexpected due to the known x ray and uv variability. In
addition studies of the polarization of PKS 2155 are
under way.

Background Features
-------------------

Randy Gladstone reported on unexpected periods of high
charged particle background at night over Australia.
These may be due to military radars causing precipitation of
particles.


EUVE ARCHIVE ADDITIONS AND UPDATES
----------------------------------
New files have been added to the EUVE Public Archive.

Updated  EUVE_bibs document: new available publications

EUVE PUBLIC ARCHIVE RELEASES 2 NEW WHITE DWARF SPECTRA

The EUVE Public archive has released the background subtracted 
spectra of the white dwarf stars WD1845+019 and WD2309+105 in the 
short, medium, and long wavelength spectrometer. These spectra
show unexpected absorption features newar 206A which will be
used as a new calibration point.

EUVE to be featured on NASA Select
----------------------------------

NASA will feature the new results from EUVE on the October
8 NASA Select Astronomy update.
