[vsnet-alert 5855] BR Lup superoutburst

BR Lup superoutburst

   The SU UMa-type dwarf nova BR Lup is undergoing a superoutburst.
The object has now attained the peak brightness.  Since the present
superoutburst is very favorably situated, long time-series observations
are wanted to precisely determine the superhump period and its variation.
The last likely superoutburst was observed in 2000 December, but was
insufficiently followed because of the poor seasonal condition.
