[vsnet-alert 11429] Re: V2672 Oph rebrightening

[Hiroyuki Maehara]

 I performed time-resolved photometry of the nova last night 
(Aug. 24.446-24.567UT). The data show a flare during 24.47-24.49 (UT).
The amplitude of the flare is ~0.35 mag. But no superhump-like 
modulations are seen in the data.
