COMET P/2006 Q2 (LONEOS)
     An apparently asteroidal object discovered in the course of
the LONEOS survey (discovery observation tabulated below), and
posted on the 'NEO Confirmation Page', has been found to show
cometary appearance by other CCD astrometrists.  P. Birtwhistle
(Great Shefford, Berkshire, U.K., 0.40-m f/6 Schmidt-Cassegrain
reflector) reports that his stack of images (total exposure time 44
min) from Aug. 29.9 UT shows that the object has a 9"-diameter coma
(FWHM 4".7) and a faint tail about 30" long (initially in p.a. 180
deg but then curving back after 7" in p.a. 230 deg). Several long
exposures by J. Young with the 0.61-m f/16 Cassegrain reflector at
Table Mountain around Aug. 30.2 show a coma with diameter 8" and a
broad tail 26" long in p.a. 215 deg.  Shorter exposures by
Birtwhistle and Young show the comet's head to be essentially
stellar in appearance.  Long exposures by Young on Aug. 31.22-31.30
continue to show a tail about 26" long in p.a. about 215 deg, with
a coma diameter of 4"-5".  Images taken by L. Buzzi (Varese, Italy,
0.60-m f/4.64 reflector) around Aug. 31.0 show a broad, short tail
about 10" long in p.a. about 180 deg.

SUPERNOVA 2006eo IN MCG -03-12-15
     Further to IAUC 8741, H. Khandrika and W. Li report the LOSS
discovery of an apparent supernova on unfiltered KAIT images taken
on Aug. 26.51 (at mag 18.2) and 28.50 UT (mag 18.6).  SN 2006eo is
located at R.A. = 4h33m21s.94, Decl. = -18o40'36".8 (equinox 2000.0),
which is 7".1 west and 1".3 north of the nucleus of the galaxy MCG
-03-12-15.  A KAIT image taken on Feb. 9.20 showed nothing at this
position (limiting mag 19.0).
