(cba:news) SDSS 1627+12... and GW Lib

[Joe Patterson]

Dear CBAers,

Well, Tom found superhumps in this interesting star last night.  The 
period is long enough to merit special attention, and placement in the 
sky could hardly be better.  Great target for borealites.

As for australites, oh, it's GW Lib!  The star is back flashing its 2.1 
hr waves in the light curve, it's a great target for those southern May 
nights, and we'd like to track that wave throughout the observing season.

Later on today, I'll send info on MV Lyr.  Jerry Foote and Bob Koff have 
obtained some very nice data, and I'll test for the orbital signal which 
would be the signature of reprocessing.  My quick study of the first two 
nights suggested no (which is interesting too, because it sets a limit). 
  But I'll study further...

joe

Time-series photometry last night shows this star is superhumping.
Amplitude is 0.2 magnitudes, and a crude period analysis gives 0.109
days, or 2.61 hours.
