[vsnet-outburst 8957] GZ Cnc superoutburst?

[Taichi Kato]

   Eddy Muyllaert reported an outburst of GZ Cnc.  According to
AAVSO MyNewsflashes, the outburst has lasted at least for three days.
If these observations are correct, the present outburst is most likely
a superoutburst (wanted, of course!).

   The object also underwent a most likely superoutburst in late 2007
December.  This outburst was recorded by Martin Nicholson and ASAS,
but was not timely observed for superhumps (cf. [vsnet-alert 9783]
GZ Cnc superoutburst?)

   The present outburst would provide first-ever opportunity to
record superhumps in this supposed SU UMa-type dwarf nova.
Time-resolved photometry is strongly encouraged (though not very
suited for long photometric sessions).
