COMET C/2006 A1 (POJMANSKI)
Grzegorz Pojmanski, Warsaw University Astronomical Observatory,
reports his discovery of a diffuse comet with a coma diameter of 1'
(FWHM) on 3-min CCD frames (pixel size 14".8) taken on 2006 Jan. 1
and 4 with a 180-mm-focal-length f/2.8 telephoto lens (+ V filter)
in the course of the All Sky Automated Survey at Las Campanas;
Pojmanski subsequently identified ASAS images of the comet taken on
2005 Dec. 29. S. Roland (Montevideo, Uruguay) writes that 20-second
CCD exposures taken with a 0.46-m prime-focus telescope confirm the
cometary nature of the new object, with a coma diameter of about 1'.
More than seven hours after Pojmanski reported his find to the
Central Bureau, K. Cernis reported (apparently independently) that
he has found an object on ultraviolet SWAN/SOHO website images taken
on three nights (back to 2005 Dec. 25) showing a motion consistent
with that of C/2006 A1.
