SPECIAL ALERT NOTICE ON CATACLYSMIC VARIABLES
Dear Observer:
February 8, 1994
2337+56 NOVA CASSIOPEIAE 1993 [V705 Cas]
This bright nova, discovered on December 7.47 UT by Syuichi Nakano of Japan at photographic magnitude 6.5 (see AAVSO Notice 179), has been very well monitored by observers worldwide. Its optical light curve, created from observations reported to the AAVSO, indicates it brightened to about visual magnitude 5.7 by mid·Oecember, and then has slowly declined to magnitude 8.4 by February 7, with fluctuations as much as 1 magnitude in amplitude.

1425-50 NOVA LUPI 1993
We have been informed by our member William Liller, Vina del Mar, Chile, of his photographic discovery, using PROBLICOM, of a nova in Lupus at magnitude 8.0 (average of two photographs, TechPan film plus orange filter) on September 19.02 UT. The 1950 position, precessed from the equinox 2000 measurements provided by R.H. McNaught and G. J. Garradd, Anglo-Australian Observatory, is
RA 14h 28m 26.04s Decl. -500 57' 18.2"
