This vsnet notification brings a new target into the morning sky for
possible coverage. The sky position and timing is poor, but with
multiple longitudes, we might be able to decipher it. It's certainly a
Speaking of which... Tom Krajci has reminded me of OT0208+37, which he
has been covering for 3 nights. The results show this star to have a
remarkable triply-periodic power spectrum - at frequencies of 34, 51,
and 102 c/d. It's possible that this is just the very complex waveform
of an unseen orbital signal at 17 c/d... and then again, it could be
something else. Let's find out! It's still bright enough to observe,
if you don't mind a little moonlight.
OT J102842.9-081927 outburst!
CRTS detected this object (= CSS090331:102843-081927) in outburst.
The object underwent a superoutburst in 2009 March-April and was identified
as an ultrashort period (Psh = 0.0381 d), hydrogen-rich object similar
to EI Psc and V485 Cen.
The brightness of the current outburst suggests a superoutburst.
