[vsnet-alert 4292] SW UMa superhump regrowth

SW UMa superhump regrowth

  From the data on SW UMa observed at Kyoto on Feb. 26 and 27, 
we can clearly see humps again which diminished on Feb. 24 and 25.
The amplitude of the hump is over 1.5 mag.  We also found that 
the phase of the hump peak is not consistent with that of the earlier 
one when we folded the light curves with the superhump period, 
there is 0.5 phase difference between them.  The lightcurve
of the regrowth of humps is seen at:

  Tonight we are having a run on SW UMa and SW UMa is still bright.
The observations on tonight and the next night are very important 
to study the superhump and the late superhump of SW UMa, 
so the follow-up observatios are strongly urged.

Regards,
Makoto Uemura
on behalf of SW UMa collaboration team
