The recently discovered ultra-short orbital period SU UMa-type dwarf nova
seems to be entering a stage of rapid decline following the superoutburst.
Observers are strongly urged to monitor for possible rebrightening(s)
expected a week (?) later.

(*) Most observers use photographic sequence by Antipin (unless otherwise
indicated), which probably gives 0.5-1.0 mag fainter than the real
V magnitude.
