PTF1 J071912.13+485834.0: normal or precursor outburst
Ken Menzies, Tamas Tordai and Itoh-san have reported the observations.
The object was 16.1 mag on Dec. 30 and has shown orbital-like modulations
whose period is 0.01860 (1) d and amplitude is 0.05-0.06 mag. The period
agrees with the orbital period of 0.01859(1) d. Thus this outburst is a normal
or precursor one.
Judging from the maximum magnitude of 15.3 mag, this might be a precursor
outburst, so additional observations are recommended.
