[vsnet-alert 3798] UV Gem outburst

UV Gem outburst

   The dwarf nova UV Gem has been found to be in outburst on Dec. 8 and 9
images (taken by M. Uemura and T. Kato).  This observation clearly
demonstrates the shorter outburst cycle length than reported before.
Based on three recent outbursts (October. 28-29, Nov. 10-11 and Dec. 8-9,
all detected and observed by P. Schmeer and by us), we propose the possible
recurrence time of 14 d, which supports the idea of the short recurrence
time by P. Schmeer, which was proposed as the alternative explanation of
the Nov. 10 outburst).

   The short recurrence time and low outburst amplitudes, together with
the existence of long, bright outbursts (as reported in 1998 April, reaching
mv=14.2, G. Hanson) make UV Gem as a very promising candidate of an
SU UMa-type dwarf nova.  Time-resolved photometry during the present and
successive outbursts is strongly encouraged.
