Re: SDSS J081207.63+131824.4 superoutburst

   Ian Miller has reported further observations.  The period determined
from these observations is 0.0786(1) d, which is far shorter than what
was detected during the 2008 superoutburst (see Pdot paper).
Re-examination of the 2008 data has shown that at least some part of
observations can be expressed by a period of 0.0774 d.
It is very important to know whether the 2008 determination of the
period was somehow incorrect (due to the gap in observation), or
we are currently having a different period (just as in ER UMa).
Continued observations are encouraged!
