COMET P/2000 R1 (SHOEMAKER-LEVY 5)
     The LINEAR team reported that one of their objects observed on
Sept. 6 was cometary, and T. Spahr and the undersigned noted that
this was about 0.6 deg northwest of the prediction for P/1991 T1 =
1991z = 1991 XXII (MPC 29882, 39661), corresponding to Delta(T) =
-1.4 day.  Following a request from the Central Bureau, D. Balam
reports that images taken with the 1.82-m Plaskett telescope of the
National Research Council of Canada show this object to have a
well-condensed coma and a fan-shaped tail extending 30" in p.a. 250
deg; his R magnitude given below was obtained in a 10" aperture.
