Subject: [vsnet-alert 1819] Superhump of V2051 Oph was detected

Dear observers,

PDM analysis by Kato using CCD observation by Kiyota on May 20-22 (posted to 
vsnet-obs) 
indicates that superhump period of V2051 Oph is around 0.0642d.

This period is a little bit longer than orbital (eclispse) period.
So, we conclude that V2051 is one of member of UGSU (SU UMa type).
