[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
