SDSS J124058.03-015919.2: dip in superoutburst

     Josch Hambsch, Crimean Astrophys. obs. team, Stephen M. Brincat,
Kiyota-san and Itoh-san have reported the observations.
     This object rapidly faded on May 4th. AM CVn stars with a long orbital
period often show a double superoutburst, which is composed of the 1st
superoutburst with early superhumps and the second one with ordinary
superhumps. This object will be brightened again within a few or 10 days.
In the rising part of the next superoutburst, we will be able to observe
growing superhumps. Thus, daily observations are strongly encouraged.
