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 on behalf of the VSNET AL Com collaboration team
