  The most recent outburst was reported in 2000 October, which may have been
a superoutburst.

[From vsnet-alert 2239]

   DM Dra was discovered by Stepanyan as SVS 2426.  The low resolution
spectrum taken during the outburst revealed the OB-type (consistent with
the dwarf nova classification).  Stepanyan reports the object is visible
on POSS at mag 20.  Magnitude reports by Stepanyan:

    JD        mpg
  2441119    <19.5
    43608    <19.5
    43613    <19.5
    43670    <19.5
    43965     15.5  spectroscopic observation done
    44054    <19.5
    44067    <19.5
    44071    <19.5
    44075    <19.5

  Quiescent CCD photometry by Howell et al. (PASP 102, 758) suggested the
presence of a 125-min period.  The object was V=20.8 at the time of this
observation.
