[vsnet-alert 9550] HS2331+3905 early superhumps in evolution

[Taichi Kato]

   HS2331+3905 early superhumps in evolution:

   Martin Nicholson's observation around Sep 5.4 UT showed evolving
early superhumps (the object was still rising).
The behavior is remarkably similar to the early-stage evolution
of early superhumps in WZ Sge itself (cf. Ishioka et al. 2002,
A&A 381, L41; available at
http://adsabs.harvard.edu/abs/2002A%26A...381L..41I

   More analysis of all reported photometric data will be soon reported
by Maehara-san.
