[vsnet-outburst 12816] Re: [vsnet-alert 13325] SDSS J220553.98+115553.7 outburst

[Hiroyuki Maehara]

 I performed time-resolved photometry of the object from J.D. 2455702.182
to 702.294. The data clearly show the presence of superhumps with amplitudes
of ~0.2 mag. Further observations are encouraged.
