Dear Colleagues,
Selected CCD results:
1556+33 VAR21 CRB 2450581.4541 1997-05-12 0.9541 14.05,
superhump maximum
1556+33 VAR21 CRB 2450581.5284 1997-05-13 0.0284 14.15,
superhump maximum
Despite the unstable weather during the time series the light curve
clearly show superhumps.
The amplitude is about 0.3 mag.
The night May 13-14 I got a new time series on Var21 CrB. The data not
reduced yet.
1621+39 VAR43 HER 2450581.4680 1997-05-12 0.9680 <15.5
