[vsnet-campaign 404] DH Aql outburst (super?)

DH Aql outburst (super?)

  Rod Stubbings reports that the SU UMa-type dwarf nova DH Aql is undergoing
a bright outburst.  The last superoutburst was observed in 1999 April
(mv=12.4, Pearce).  The superhump period of this object has not been well
established.  Because of the excellent visibility, intensive time-resolved
photometry to accurately determine the superhump period is strongly
encouraged.  The present outburst is selected as one of priority targets
of the VSNET collaboration team.  Please report your progress to
vsnet-campaign-dn, and data to vsnet-campaign-data.
