[vsnet-alert 83] outbursts of CY UMa and UV Gem

[tkato@kusastro.kyoto-u.ac.jp]

CY UMa

  We obtained some time-resolved CCD photometry on two occasions during
the past superoutbursts (1991 Dec. and 1993 Mar.).
  A preliminary period analysis has yielded the best estimate of the
superhump period of 0.0724 +/- 0.0005 day.  However, this value still
has relatively large uncertainty because of short baselines, which
did not exceed two days.  (T. Kato et al. in preparation; please note
that the period given in VSOLJ Var. Star Bull. had a large error owing
to unavoidable errors in visual observations)

  The present probable superoutburst of CY UMa would provide one of the
best chances to refine the superhump period.  Observations are therefore
highly encouraged.

UV Gem

  Another poorly known dwarf nova, UV Gem, is caught in outburst by
M. Iida by his CCD monitor (see vsnet-obs message).
