SW UMa: super-QPOs during rapid decline

  In the light curve on March 1st and 2nd we discovered 
super-QPOs on the prominent superhumps.  

  The super-QPOs are clearly seen, in particular, on March 1st 
and they have the period of about 10min.  We can see more complicated 
profile of humps and super-QPOs in the light curve on March 2nd.

  The light curve on March 1st can be seen at the VSNET SW UMa page:

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

  The super-QPOs have been seen only in the very early stage of the 
superoutburst before this discovery.  We can get more information 
about the nature of the super-QPOs through the tonight and next night 
observations.  Unfortunately, the weather will become worse tonight 
in Kyoto.  The follow-up observations are strongly urged.
