[vsnet-alert 4453] TV Crv rare outburst

TV Crv rare outburst

   Rod Stubbings report that the large-amplitude SU UMa-type dwarf nova
TV Crv (Tombough's variable) is undergoing an rare outburst, presumably
a superoutburst.  The latest outburst (superoutburst) of TV Crv was observed
1998 May - June.

   Coordinates: 122024.16 -182702.6 (2000.0)

   The Kyoto team have just started CCD photometry, and confirmed the
outburst.

   Although superhumps have been reported (Psh=0.0650d, Howell et al. 1996),
unfavorable seasonal conditions in previous superoutbursts have made
long time-series observations difficult.  We strongly encourage observers
to concentrate on this object by taking the present rare opportunity, very
favorably located in the midnight sky, and wish for another successful
VSNET collaboration, as we have had in IY UMa (TmzV85), QY Per etc.
