AH Her (UGZ): Sep 5.88, 11.6; Sep 6.88, 11.6. In outburst.
CY Lyr (UGSS): Sep 6.93, 13.6:. In outburst? (Near limit.)
RU Peg (UGSS): Sep 5.88, 12.7. At minimum.
IP Peg (UGSS+E): 21 observations from Sep 6.830 to Sep 7.024 UT.
This dwarf nova was seen in outburst (maximum magnitude 12.5).
An eclipse was observed and time of mid-eclipse was 22h38m UT
as deduced from the tracing paper method. The falling and ring
part of the light curve was used (the minimum was not seen).
This timing agree well with a minimum observed by M. Yamada
(Ishikawa, Japan) at Sep 5 19h01m UT (communicated by T. Kato).
The orbital period of IP Peg is 3h48m.
TZ Per (UGZ): Sep 6.94, 13.2. In outburst.
TY Psc (UGSU): Sep 6.96, <13.5:.
OTHER VARIABLES
AX Per (ZAND+E): Sep 5.89, 11.7. Faint.
FG Sge (*): Sep 5.89, 10.1; Sep 6.83, 10.1. Unusually faint.
