[vsnet-alert 12054] Re: OT J162520.3+120309 = Catalina transient

[Gianluca Masi]

Dear Colleagues,

after following this star for about 3 hours, doing time resolved 
photometry, I see that the source is showing some periodic modulation 
(with a total amplitude of 0.05 mag), while fading just a bit over the run.

Assuming a single peak light curve, I get a period estimate of 1.05 
hours (a double peak curve would suggest a double period).

The mean unfiltered magnitude is about 13.0.

More later, run still ongoing,
Gianluca
