Possible Nova in Pup

    Kazuyoshi Kanatsu (Matsue, Shimane, Japan) reports the discovery
of a new variable star, which is likely a nova based on the absence
of apparent counterparts on his previous image, DSS and 2MASS.
Kanatsu reports no apparent movement between his two exposures and
no registered minor planet at this position.

    The coordinates reported by Kanatsu are:

    RA  07h 37m 58s
    DE -25d 56m 51s
    (J2000.0)

    The object is located 50" NE of GSC6543.2322.

    Confirmatory observations and, if confirmed, spectroscopy are very
urgently requested.

    We use the tentative designation PUPnova2000 in this report.
