PERIODIC COMET HALLEY (1982i)
     K. J. Meech, University of Hawaii, reports that strongly
condensed images were observed with the 2.3-m reflector on Nov.
26.  Her preliminary analysis gave a Mould V magnitude of 19.6
within a diaphragm of radius 5".

     Total visual magnitude estimates: Nov. 28.29 UT, 7.7 (A. Hale,
Las Cruces, NM, 10 x 50 binoculars); Dec. 7.78, 8.4 (J. Shanklin,
Cambridge, England, 0.33-m reflector); 9.13, 7.5 (Hale); 9.82, 8.2
(P. Schmeer, Bischmisheim, West Germany, 0.20-m reflector); 11.97,

7.5 (G. Garradd, Tamworth, N.S.W., 7 x 50 binoculars);


COMET ICHIMURA (1987d1)
     Total visual magnitude estimates: Nov. 28.26 UT, 8.4 (A.
Hale, Las Cruces, NM, 10 x 50 bin.); 29.32 UT, 7.9 (R. A. Keen,
