As reported in [vsnet-campaign-dn 3590], Var73 Dra, an unusual SU
UMa-type dwarf nova in the period gap, experienced an superoutburst
in April. 

Nyrola team kindly sent us their 2 night data sets on April 18/19 and
22/23. Combined this data with Kyoto data sets, the outburst continued at
least from April 15 to April 27. The magnitude was gradually decrining
from ~15.3 mag to 16.1~mag during 12 d with the averaged rate of 0.06
mag/d. 

Anyway, recent four superoutburst including this one show the unusually
short supercycle of ~60 d.  

Regards,
Ryoko Ishioka
