COMET P/2007 O2 = P/1998 U2 (MUELLER)
L. Buzzi and F. Luppi, Varese, Italy, report the recovery of comet
P/1998 U2 on IAUC 8859, being slightly diffuse on CCD images obtained 
with a 0.60-m reflector, with confirming CCD images by Peter Birtwhistle 
(Great Shefford, Berkshire, U.K., 0.40-m reflector).

and on MPC 51823 is Delta(T) = +0.3 day.

SUPERNOVAE 2007gc AND 2007gd
Further supernova discoveries reported by The "Nearby Supernova Factory" 
collaboration have been announced on The Astronomer's Telegram 1150 and 
designations added on CBET 1011. These were recorded on images obtained 
on July 18 UT using the QUEST-II
camera on the Palomar Oschin 1.2-m Schmidt telescope, operated by the 
Palomar-QUEST Consortium. The R-band discovery magnitudes and astrometry 
were derived from comparison with the USNO-B1.0 catalogue.  The 
following table summarizes the discovery information:
