D. E. Machholz (Colfax, CA).  Coma diameter 2' moderate degree of
  condensation (position and physical measurements made with a
  0.25-m reflector at 64x).  Motion < 1 deg/day eastward.
G. Garradd (Siding Spring).  0.5-m Uppsala Schmidt telescope + CCD.
  Coma diameter 1', with a 3' tail in p.a. about 320 deg.  Position
  rough (center of comet uncertain within overexposed coma).
R. H. McNaught and G. Garradd (Siding Spring).  1.0-m f/8 reflector
  + CCD; 6' tail in p.a. 245 deg (10-sec exposure); magnitude of
  nuclear condensation 14.4.
