[vsnet-outburst 10592] BC UMa variation (Oksanen)

[Taichi Kato]

   Oksanen's report.  The variation is indeed present, but does not
seem to be very regular as in early superhumps.  More observations
are naturally requested.

I observed BC UMa at Hankasalmi. The star was bright (V=12.05) and
showed irregular variation. The intended all-night run ended midnight
because of a software glitch, so it is not possible to see if the
humplike feature on light curve was periodic or not. Should this star
observed more? Though the weather is again cloudy in Finland.
