1.2 Observation Log
-------------------
EUVE observed eight different targets for regular observations over the course of
the fourth quarter of 1999 including Jupiter, MCT0455-2812, IIPeg, Procyon, TON S180,
J0443 08, ACO0950, and ACO1366.
Additional observations were made for an engineering survey and special targeting
was arranged for the Leonid meteor shower.
Details and previous observation information are available at:

2. EUVE Science News
====================
2.1 Science Highlights
----------------------
EUVE science highlights for the third quarter of 1999 are:
October: EUVE Observations of the Venus Dayglow
Time-Resolved EUVE Spectroscopy of AR UMa
EUVE Spectroscopy Shows Iron in G191-B2B Atmosphere has a
Depth-Dependent Abundance
Details and previous months' highlights are available at:
http://www.cea.berkeley.edu/~science/html/Resources_high.html
2.2 EUVE Cycle 8 TAC Results
----------------------------
The EUVE project released a call for proposals on August 11, 1999.
Forty proposals were received with a total of 45,300 ksecs requested. The
oversubscription rate for cycle 8 is 5 times the available year (8,550 ksecs
after allotted Director's Discretionary Time and engineering/calibration time).
Nine proposals were awarded type I time totaling 5,180 ksecs. Beginning
in March, the EUVE Project will begin scheduling observations of the
selected targets including: New Comet, Mercury, EX Hya, EUVE J006+29.0,
EUVE J0932+26.9, EUVE J0613-23.9, Virgo, LB 9802, HD146361, 44 Boo, and
PSR J0659+1414. In keeping with the strategic plan of the observatory,
a number of these targets will be observed for extended periods of up to
1000 ksecs. Several other targets were approved as type II programs, and
will be observed as possible by EUVE.
For a complete target listing, see
http://www.cea.berkeley.edu/~science/html/Observing_sched_cycle8.html
2.3 EUVE Science Advisory Board (ESAB) Public Meeting Held
-----------------------------------------------------------
The EUVE Science Advisory Board (ESAB) held a public meeting on
the last day of the American Astronomical Society meeting in Atlanta, GA,
Saturday, January 15, 2000, from 1-2 p.m. ESAB members discussed
developments and future plans for the EUVE project.
Much of what was discussed at the meeting is in the he ESAB FY99 review
of the EUVE Project at UCB. The report is available at:
