Things you can do when is cloudy

Lack of good weather encouraged me to do some preliminary analysis. Our last outburst appeared to be quite long and bright. I compared it withvmean profile of outburst derived from 2004-2005 observations. See the picture below. The red and green points show January 2009 and mean 2004-2005 profiles of the outburst, respectively.



It is clear that our newest explosion was about 0.5 mag brighter and lasted about 1 day longer than a typical outburst from previous seasons.

Another pecularity is current supercycle length. We are waiting for the superoutburts for at least 23 days. This value is significantly higher than 19-day supercyle of RZ LMi.

  1. How does M dot behave in these objects? If roughly constant then I would naively predict that next superoutburst will be ~19-day after recent "strange" outburst.
