ZTF20acyxwzf: likely periods

   Kyoto U. team, Kubotera-san and Itoh-san have
reported observations.  In the data of Kyoto U.
team on Feb. 10, there were modulations (0.14 mag)
with a period of 0.0414(5) d.  An analysis of
the data before rapid fading yielded a period
of 0.0404(3) d (confirming the result in
vsnet-alert 25342).

   If the object is indeed an AM CVn star, these
periods are longer than that of GP Com (0.0323 d).
Spectroscopic observations to test the presence
of hydrogen lines (i.e. EI Psc stars) are very
important.
