COMET WILSON (1986l)
     Christine Wilson reports her discovery of a comet on plates
taken with the 1.2-m Schmidt telescope at Palomar in the course of
the new Sky Survey.  The object appears diffuse with some
condensation and an apparent short tail to the southeast.

G. Schwartz, R. McCrosky, and C.-Y. Shao (Oak Ridge Observatory).
   Prediscovery images were found on two Damon patrol plates taken
   on Aug. 4; the Aug. 6 plates were taken with the 0.41-m
   astrograph and were measured by Shao.
C. Pollas (Caussols).  CERGA 0.9-m Schmidt telescope; beginning
   and end of trail.
C. Wilson (Palomar Observatory).  Beginning and end of trail.
   Assistance from and communicated by A. Maury.

     Visual searches around Aug. 6.2 UT by C. S. Morris and D. W.
E. Green indicated that the comet could then be no brighter than
m1 ~ 10.5.


NSV 6708
     W. Wenzel, Sonneberg Observatory, reports that 81 sky patrol
exposures taken by C. Hoffmeister in 1935-1936 and 1952-1953 show
a mean mpg = 11.5, with no variation larger than 0.5 magnitude.
R. H. McNaught, Siding Spring Observatory, provides further visual
magnitude estimates (IAUC 4233): July 18.38 UT, 7.7; 21.50, 7.3.


PERIODIC COMET HALLEY (1982i)
     Further total visual magnitude estimates (cf. IAUC 4236): July
22.70 UT, 11.5 (R. Fleet, Harare, Zimbabwe, 0.35-m reflector);
24.70, 11.2 (Fleet); 26.70, 11.4 (Fleet); 28.72, 11.2 (J. Campos,
Durban, R.S.A., 0.20-m reflector); 30.71, 10.9 (Fleet); 31.70,
10.8 (Fleet).
