COMET C/2004 R2 (ASAS)
G. Pojmanski, Warsaw University Astronomical Observatory,
reports the discovery by the 'All Sky Automated Survey' (ASAS) of a
comet on CCD V images taken on Sept. 3.40 UT with the ASAS-3V
instrument (a 200-mm-f.l., 70-mm-aperture, f/2.8 telephoto lens;
pixel size 14".8) at Las Campanas (measurements of ASAS-3V images
given below). A. Hale (Cloudcroft, NM, 0.20-m reflector) reports
total visual mag 10.9 and coma diameter 2'.5 (diffuse without
condensation) on Sept. 9.47.
