[vsnet-superoutburst 380] (No Subject in original)



Dear colleagues,

  The combined data from 18.66 May to 23.34 May shows gradual decline
trend at the averaged rate of ~0.2 mag/day since 19.46 May. 
(see  http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/DNe/alcom0105.html)

 The early superhump period based on the  19 - 22 May data (the Kyoto team, 
G.W. Billings, R. Novak & P. Sobotka and B. Martin) is  0.05672(2) d, which
is consistent with the early report [vsnet-campaign 920] with in error.
Averaged light curve in the VSNET AL Com page will be up-dated  later.

 The light curves by  R. Novak & P. Sobotka and B. Martin still show the humps
with a small amplitude (0.05-0.1 mag) and double-peaked profile. The feature of
humps are changing day by dat. Sometimes single-peak and slightly 
large-amplitude humps appeared. But the clear "normal" superhumps don't begin.

Just now R. Novak informed that their last night observation shows 
0.8mag/d decline. Does it show a rapid change of the outburst nature?
More observations are very strongly urged.

Regards,
Ryoko Ihsioka
