[vsnet-campaign-dn 2405] IY UMa: superhumps


    The period analysis using recent light curves (May 11-13) 
provided a superhump period of 0.07584(4) d.  This is the average 
superhump period observed during the 2000 outburst, and indicates 
that the period is now decreasing.

    Superhumps are still very prominent.  
    Eclipses observed on May 12 were apparently asymmetric, 
	indicating a tidally distorted disk.
    The object is now gradually fading.

Regards,
Makoto Uemura
