[vsnet-outburst 9802] Superhumps in OT_J213122.4-003937 (new cataclysmic variable in Aqr)

[Hiroyuki Maehara]

Dear colleagues,

 A. Miyashita (Seikei High School, Tokyo, Japan) sent us time-series
data of new DN in Aqr obtained on Dec. 19.  I carried out time-resolved 
photometry of this object on Dec. 19 and 20. The data show superhumps 
with an amplitude of 0.1 mag which indicate that the object is a new 
SU UMa-type dwarf nova.
 The best estimated superhump period is 0.0696(2) d, though aliases
are not completely excluded.

Further observations are strongly encouraged.
        
Best regards,
Hiroyuki Maehara
