Dear CBAers,

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 
fascinating star.

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.
