[vsnet-alert 9378] SDSS J122740.83+513925.0

[Hiroyuki Maehara]

Daer Colleagues,

According to cvnet-outburst messages, SDSS J122740.83+513925.0 is 
in outburst. Tonny Vanmunster reported the detection of two eclipses 
with a depth of 0.5 mag on June 4/5. He also reported that orbital 
period of this object is 0.0624 +/- 0.0001 days.

I carried out 2 hours time-series photometry of this star on Jun 7.
The data show large amplitude (~0.4mag) hump just after a eclipse.
Orbital phase of the hump is different from that of the humps shown
in Vanmunster's data on June 4/5. 
The hump shown in tonight's data seems to be a superhump.

Follow-up time-series observations are encouraged.

Best regards,
Hiroyuki Maehara
