COMET SPACEWATCH (1992h)
     D. Rabinowitz, Lunar and Planetary Laboratory, University of
Arizona, reports the discovery of a comet with the moving-object
detection software on the Spacewatch telescope at Kitt Peak.  J.
Scotti provides the precise positions below.  The comet is described
as diffuse, with no resolvable tail, the coma being of
diameter 14" on May 1 and 17" on May 2.

HV VIRGINIS
     H. Mendelson, E. M. Leibowitz, N. Brosch, and E. Almoznino,
Tel Aviv University, report:  "During Apr. 28.77-29.06 UT, we
monitored HV Vir continuously with the Wise Observatory CCD camera.
The star's light curve shows clear periodic variations, of which we
have recorded 5 complete cycles in the B and R photometric bands.
The period is 86.1 +/- 2.2 min and the amplitude from maximum to
minimum is 0.05 mag.  Minima are at phase 0.65 with respect to the
maxima."
