1. HUBBLE SPACE TELESCOPE CAMPAIGN (0203+56 UV PER & 0324+58 AF CAM)

---------------------------------------------------------------------------
1. HST TO OBSERVE UV PER AND AF CAM --- Janet A. Mattei, Aaron Price
We have been informed by Dr. B. Gaensicke at UK that the Space
Telescope Imaging Spectroscope (STIS) aboard the Hubble Space
Telescope is scheduled to do ultraviolet spectroscopy of UV Per and AF
Cam in the following exact dates and time:
0203+56A UV Per Oct 11 2002 20:25:20 UT to 21:03:27 UT
0324+58 AF Cam Oct 13 2002 20:06:11 UT to 20:43:46 UT
On behalf of the HST Program team, of astronomers in Europe and in the
US, Dr. Gaensicke is requesting our observers help in monitoring these
cataclysmic variables closely before, during, and after the scheduled
times so that they can have "realiable information" on the behavior of
the stars for the correlation and analysis of HST data.
All CCD Observers: Please observe these objects several times per
night with a V filter. Particularly during the HST scheduled
observations please take as many high quality images as possible in V.
European and Asian observers: The scheduled observations will occur
while you are in darkness and North America is awash in daylight. So
your observations are critical!
Both stars are presently at quiescent and are quite faint. UV Per is
around V=17-19! AF Cam is between V=16.5-18! Be prepared to track
and/or stack lots of images. Thanks to Ron Zissell (ZRE), Roger
Diethelm (DRG), and Steve Robinson (RSE) for already sending in CCD
observations of these two objects.

2. WW CET RXTE SATELLITE CAMPAIGN UPDATE --- Janet A. Mattei, Aaron Price
Our observations are really starting to pile up. Keep 'em coming!
Below are the latest observing times for RXTE. Please observe WW CET
every night and as often as possible during the following windows.
Think about it: while your CCD is opened up at WW CET, in space RXTE's
detectors will also be counting photons from the same source!
OCT 11 15:43:00 to 16:27:00
OCT 12 15:28:00 to 16:14:00
OCT 13 13:25:00 to 14:22:00
OCT 14 14:55:00 to 15:41:00
OCT 15 14:37:00 to 15:23:00
OCT 16 14:20:00 to 15:06:00
OCT 17 14:03:00 to 14:50:00
Please submit your data to AAVSO HQ as soon as possible. Special thanks to
Peter Nelson (NLX), Robert James (JM), Tim Hager (HTY), Frank Sheder (SFK),
Thomas Richards (RIX), Mike Koppelman (KMP) and Chuck Pullen (PCH) for already
providing excellent coverage.
Dr. Baskill's web page covers the project in depth along with what he is
trying to learn.

Please observe and report your data to the AAVSO as soon as possible.
