COMET C/2006 A2 (CATALINA)
     An apparently asteroidal object discovered by the Catalina
Sky Survey (discovery observation tabulated below), and posted on
the 'NEO Confirmation Page', has been reported as apparently
cometary by several CCD observers, including J. Young (Table
Mountain, 0.6-m f/16 Cassegrain reflector; coma diameter about 6"
in poor seeing conditions on Jan. 23.2 UT), J. E. McGaha (Tucson,
AZ, 0.62-m f/5.1 reflector; six stacked 60-s images taken on Jan.
23.2 show a soft 4" coma and no tail, but also large changes in
brightness of about 0.7 mag over about half an hour), and J. Ticha
and M. Tichy (Klet, 1.06-m KLENOT telescope; diffuse with a coma
diameter of 12" on images taken on Jan. 23.8).

orbital elements, and an ephemeris appear on MPEC 2006-B48.

SUPERNOVAE 2006O AND 2006P
     Two apparent supernovae have been discovered on unfiltered CCD
frames:  2006O by D. Rich (Hampden, ME, 0.31-m reflector) and 2006P
by D. R. Madison and W. Li (LOSS/KAIT; cf. IAUC 8661).

Additional approximate magnitudes of 2006O in UGC 633:  2005 Nov.

Nothing is visible at the location of 2006O on Palomar Digital Sky
Survey images from 1989 (limiting red mag 20.0) and 1988 (limiting
blue mag 19.9).  Additional KAIT magnitudes of 2006P in MCG
-02-9-29:  2005 Dec. 9.21, [19.0; 2006 Jan. 9.22, [18.0; 24.19,
