[vsnet-alert 23875] Re: ATO J061.1478-31.0634 = Gaia19fes: orbital period

[Berto Monard astroberto13m@gmail.com via vsnet-alert]

Hello Patrick,

to get proper confirmation on the period of this star, it needs to be
revisited with long duration timeseries during quiescense. For the moment
the period seems to be around 0.2453d showing a double hump profile..
Most likely it's just another UGSU type CV.

Regards,

Berto Monard / CBA-KKO
