   Ian Miller has reported observations on two nights
(Jan. 29 and 30).  Low-amplitude modulations were
recorded.  The most likely period was 0.0592(2) d.
The value is slightly different from Vanmunster's
value in vsnet-alert 22969.  We will have a better
period when more data become available.

   After identification as an SU UMa-type dwarf nova,
the true CV is most likely the fainter component.
My initial suggestion of an SS Cyg star was based
on the rate of decline, which was apparently affected
by the brighter (unrelated) companion.
