NY Ser superoutburst starting from standstill?

   Crimean Astrophys. Obs. team, observing at Lisnyky Obs.,
reported development of superhumps.  These superhumps
have been recorded since Mar. 22.

   It looks like that the object slightly brightened since
Mar. 16  (What happened during the gap between Mar. 18-21?)
Please continue observations since such an instance
has been probably the first recoded one.
