 Gaia20dpd: ordinary superhumps

  Andrew Simon and Kyoto U. team have reported further
observations.  The object showed ordinary superhumps
on Aug. 15-16 (amplitude 0.19 mag).
The period is 0.0564(2) d based on single-night data.
There remained some ambiguity in background trend
in Kyoto U. observation and the error may be a bit
larger.  The object is now confirmed as a genuine
WZ Sge-type star.
