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: http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/DNe/swuma00.html 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.
