Greetings, A rather disappointing series of small clouds interfered with measures of the eclipse. However, the following times were noted. All UT, no HC applied. Last pre-eclipse observation: Feb12 09 35.7 Rising out of eclipse 09 50.5 First post-eclipse observation 09 59.8 Eclipse depth was greater than 1.7 magnitudes in the CCD natural system. This suggests that the eclipse ephemeris in VSAlert 4191 is a few minutes out. If a flat bottom is to be fitted to this particular eclipse the ingress and egress must be decidedly asymmetric. Tau 3 continues to fade slowly and in a 40 minute run prior to the eclipsing star rising we did not find any superhump - but the time duration makes this observation useful only to indicate that the star had not disappeared. It appeared about 0.5 magnitudes fainter than on Feb 10. Regards, Stan ---------- > From: Taichi Kato <tkato@kusastro.kyoto-u.ac.jp> > To: vsnet-alert@kusastro.kyoto-u.ac.jp
