Dear Colleagues,

Selected CCD results:

1621+39      VAR43 HER  2450592.4249   1997-05-23   0.9249      12.91,
the night was too poor to get a time series.
1556+33      VAR21 CRB  2450592.5451   1997-05-24   0.0451      15.7,
outburst continues
1344+08      CR BOO     2450592.4145   1997-05-23   0.9145      15.9

1621+39      VAR43 HER  2450593.4645   1997-05-24   0.9645      12.92,
this Var43 Her time series clearly shows superhumps with amplitude ~0.2
mag and period about 75-80 minutes. Thus I confirm the very short
period.
1556+33      VAR21 CRB  2450593.4340   1997-05-24   0.9340      15.7,
outburst continues
