[vsnet-outburst 7812] SDSS J122740.83+513925.0: revised superhump period

[Hiroyuki Maehara]

Dear colleagues,

I observed SDSS J122740.83+513925.0 on June 7, 10, and 11.
The data show clear superhumps with an amplitude of 0.4 mag and
eclipses with a depth of 1 mag.

I performed superhump period analysis after removing the data 
during eclipses. The best estimated superhump period is 0.06444(13)
days. The orbital period estimated from eclipse minimum timing is
around 0.06297 days and the fractional superhumps excess is 2.3%.

Future observations are strongly encouraged.

Best regards,
