COMET MACHHOLZ (1978l)
     M. P. Candy, Perth Observatory, provides the following elliptical
elements, satisfying observations over a 6-day arc with residuals
1"-5":

       T = 1978 Aug. 11.251 ET   Peri. = 223.19
       e = 0.9812                Node  = 289.71   1950.0
       q = 1.7617 AU             Incl. = 130.58

The correction to the ephemeris on IAUC 3272 amounts to dR.A. = +0m.5,
dDecl. = +16' on Oct. 4.

     D. E. Machholz, Los Gatos, California, provides another total
visual magnitude estimate (25-cm reflector): Sept. 21.51 UT, 10.8.

     No precise positions have been reported for this comet.
