[vsnet-alert 24794] ASASSN-20kv superhump period

ASASSN-20kv superhump period

   Nataly Katysheva and Sergey Shugarov team has reported
observations later in the superoutburst plateau.
Thanks to their data, we could obtain a superhump period
0.05603(2) d combined with already reported observers.

   Pdot between Sep. 3 and 11 was +4.6(1.3)*10^(-5),
a moderate value for a WZ Sge system.
A re-analysis of the part before Sep. 2 yielded
a very weak signal (0.02 mag) with a period of
0.0553(1) d.  This may be the period of early superhumps.
