[vsnet-alert 847] Possible brightening of DV UMa

   Visual and CCD observations of DV UMa seem to indicate the dwarf nova
has turned to rise on Apr. 12 from its monotonous superoutburst decline.
Observations are strongly encouraged to see if this may be a part of a long
period wave or somehow related to a dip as in WZ Sge stars.  Please use
the latest VSNET V-mag sequence to avoid discrepancies caused by different
sequences.
