[vsnet-alert 2771] AK Cnc outburst

[Taichi Kato <tkato>]

AK Cnc outburst

   Gary Poyner reports that the short-period SU UMa-type dwarf nova AK Cnc is
undergoing an outburst (possibly a superoutburst).  Several previous superhump
detections were reported, but with relatively sparse temporary coverage.
Being in favorable evening target, time-series CCD photometry is recommended
(unless BC UMa erupts ;-).  Post-superoutburst rebrightening is also expected
for this short period system.  The latest reported superoutburst of AK Cnc
occurred in 1998 Februrary - March.
