IY UMa : Superoutburst in June

According to T. Kinnunen, the northern eclipsing SU UMa-type dwarf nova IY UMa (=TmzV85) was experienced an outburst (14.3mag) on February 14 (vsnet-campaign 804). The outburst was rapidly faded as observed on March 5 and 6 (vsnet-campaign-dn 576). On March 15, the Ouda team reported the object was about 16.8-17.0 mag, brighter than previously reported quiescent magnitude (vsnet-campaign-dn 585).

The next outburst was detected by P. Schmeer at about 14mag on June 14 (vsnet-campaign 976). T. Kato noticed the suggested supercycle indicates the current outburst is a superoutburst, and the long duration of this outburst supports it is a superoutburst (vsnet-campaign 978, vsnet-campaign-dn 906). The superoutburst continued at least until June 25 (vsnet-campaign-dn 938).
