0053-73 POSSIBLE NOVA IN THE SMALL MAGELLANIC CLOUD
We have been informed by the Central Bureau for Astronomical Telegrams
(IAU Circular 7995) that a possible nova near the center of the Small
Magellanic Cloud has been discovered by W. Liller of Chile. The 12.3
magnitude object appears on Technical Pan exposures taken on OCT 16.2 UT.
A CCD exposure taken by Liller at OCT 17.204 UT was used to obtain a
broadband V magnitude of 12.66 and the following position:
R.A.= 0h 56m 30.4s +/- 0.2s Decl.= -72o 36' 29.4" +/- 1.1" (2000)
Please report the object to the AAVSO as: 0053-73 N SMC 02
An AAVSO chart prepared by Aaron Price and showing the location of the
possible nova has been posted on the AAVSO web page. This chart is
accessible via the following url: http://charts.aavso.org/
Congratulations to W. Liller on this discovery!

HST TO OBSERVE CW1045+525, V503 CYG, AND BZ UMA
We have been informed by one of our colleagues that the Space Telescope
Imaging Spectrograph aboard the Hubble Space Telescope will be doing
ultraviolet spectroscopy of CW1045+525, V503 Cyg, and BZ UMa in the
coming week. The exact times of the scheduled observations are given
below:
CW1045+525 Oct 18 2002 08:56:24 UT to 09:42:47 UT
V503 Cyg Oct 24 2002 15:46:35 UT to 16:22:54 UT
BZ UMa Oct 25 2002 04:17:39 UT to 04:56:39 UT
Observers, especially those with CCDs, are encouraged to keep a close
eye on these objects leading up to and particularly during the HST
observations. Having AAVSO data available for correlation will be
very useful to our colleagues in the analysis of their HST data.
