[vsnet-outburst 12061] OT J043112.5-031452

[Gianluca Masi]

Dear Colleagues,

I finished my 5.8 hours of photometry on this star, finding a Psh 
candidate of 1.603 hours. I see another feature, which is modulated by 
an apparently shorter period of 1.586 hours, looking like an eclipse.

Data were sent to Kyoto for further analysis.

regards,
Gianluca
