  As reported by C. P. Jones, the Antipin dwarf nova Var61 Her is undergoing
one of its rare outbursts.

  The latest reported outburst occurred in 1998 November, during which
considerable light variation was reported by T. Kinnunen.  Time-resolved
CCD photometry is strongly urged to detect possible superhumps.

  The object is located at 18h 05m 46s.4, +31o 40' 18" (J2000).
The quiescent magnitude of Var61 Her is reported to be ~19 (USNO magnitude).
