[vsnet-alert 2840] Likely superoutburst of DH Aql

[Taichi Kato <tkato>]

Likely superoutburst of DH Aql

  The SU UMa-type dwarf nova DH Aql is presumably undergoing a superoutburst
as reported by A. Pearce.  The latest reported superoutburst of DH Aql
occurred in 1997 May.  Although the superhump period of 0.0805 d was
determined by Nogami and Kato (IBVS 4227), the accurate determination of
the superhump period is still pending further observations.  Time-resolved
photometry is strongly encouraged during the present bright outburst.
