HO Del superhumps

   Maehara-san and the Kyoto team (observer: Ohshima-san) have succeeded
in observing HO Del.  On Aug. 3, The object was fading at a rate
around ~1 mag/d without prominent superhumps.  The object was observed
rising on Aug. 4, with emerging superhumps.  These findings suggest that
the current outburst was caught during its precursor outburst and is
now approaching the full supermaximum.  The course of the present outburst
is similar to that of VY Aqr this year!  We call for intensive observation
during the entire course of the superoutburst, and potential rebrightening.
Further analysis will be presented by Maehara-san/Ohshima-san.
