COMET McNAUGHT-RUSSELL (1994u)
     Robert H. McNaught reports his discovery of a comet on a plate
taken by Kenneth S. Russell.  The following observations are
available:

K. S. Russell (Siding Spring).  U.K. Schmidt Telescope R plate.
  Coma diameter about 0'.1 with strong central condensation and a
  short tail.  Dense star field.  Measured by McNaught.
T. Kojima (YGCO Chiyoda Observatory).  0.25-m f/6 reflector + CCD.
  Moonlight and bad seeing; comet low in the sky.  Communicated by

SUPERNOVA 1994ad IN ESO 152-G26
     N. B. Suntzeff, Cerro Tololo Interamerican Observatory, reports
that spectrophotometry obtained on Dec. 12.2 UT with the CTIO 4-m
telescope (range 320-750 nm, resolution 700) shows SN 1994ad (cf.
IAUC 6103) to be a type-II supernova, very similar to the type-IIP
SN 1986I (Pennypacker et al. 1989, A.J. 97, 186) six weeks after
maximum.


SUPERNOVA 1994ae IN NGC 3370
     Visual magnitude estimates (cf. IAUC 6111):  Dec. 6.09 UT,
12.3 (T. Vanmunster, Landen, Belgium); 11.10, 12.7 (M. Villi and G.
Cortini, Mt. Colombo, Italy).


COMET MACHHOLZ (1994r)
     Total visual magnitude estimates (cf. IAUC 6105):  Nov. 29.32
UT, 9.8 (C. S. Morris, Whitaker Peak, CA, 0.26-m reflector); Dec.
1.09, 9.8 (J. E. Bortle, Stormville, NY, 0.32-m reflector); 1.92,
9.2 (E. Broens, Mol, Belgium, 0.35-m reflector); 3.13, 9.7 (Bortle);
10.33, 10.8 (Morris).
