PT And: still in outburst, superhumps?
Kyoto team (Ohshima-san) has reported further observations. PT And
was still in outburst on Dec. 24, but had faded by 0.8 mag in 4 d.
There were modulations which can be attributed to superhumps, but the
faintness of the object (in strong moonlight) has made identification rather
uncertain. A candidate period is 0.0564 d. The object appears to be
a WZ Sge-type dwarf nova with a very long-lasting plateau phase.
