[vsnet-obs 3601] On outbust of HO Del

   According to J. Pietz (vsnet-obs 3600), the SU UMa-type dwarf nova HO Del
is in outburst.  HO Del was first confirmed to be an SU UMa-type dwarf nova
by the Ouda team during the 1994 outburst.  The present brightness of the
outburst may suggest a superoutburst.  For observer's convenience, I have
extracted from the old vsnet log on the 1994 superoutburst of this dwarf
nova.  No secure outburst reports were received during the 1995 season.

  HO Del is located at:

  20h 36m 55s.56s  +14o 03' 08".5  (2000.0)

   Note that the position in the second volume of the GCVS 4-th ed. is
inccorect by about 1 degree (correction provided in the fourth volume).

The 1994 superoutburst  (from the vsnet log)
---------------------------------------------------------------------------
HO Del

   The V-band CCD observation on Aug. 26 at Ouda has confirmed that
the above variable is a new member of SU UMa-type dwarf novae.
   The superhump maxima occurred at 13h 05m UT and 14h 36m UT; the
superhump period is thus about 91 min.  The amplitude of superhumps
was 0.18 mag, probably still developping.
