[Vsnet-alert 8411] Re: J1556 -- immature superhump?

[Hiroyuki Maehara]

Dear Colleagues,

I performed time-resolved photometry of SDSSJ155644.24-000950.2
last night (JD 2453517.160 - 2453517.236).

Clear decline trend with a rate of about 1.5 mag/day can be seen 
in the data obtained by Nakajima-san and me.

Current outburst seem to be a normal outburst, but we cannot exclude
the possibility of a precursor.
Further observations are recommended.

Regards,
Hiroyuki Maehara
