COMET P/2010 K1 (LINEAR)
     J. V. Scotti, Lunar and Planetary Laboratory, reports his
recovery of comet C/2003 UY_275 (cf. IAUC 8247) on CCD images
obtained with the Spacewatch 1.8-m f/2.7 reflector at Kitt Peak
(astrometry provided below).  On May 20, the coma diameter was 6"
and a tail extended 0'.14 in p.a. 256 deg; on May 21, the object
was diffuse but near a bright star.

COMET P/2010 J3 = 2010 CG_6 (McMILLAN)
     February observations from the WISE spacecraft of this object
(cf. IAUC 9146) have been identified by B. G. Marsden, leading to
the following improved elliptical orbital elements (from MPEC
2010-K20):

                    Epoch = 2010 Sept. 1.0 TT
     T = 2010 Aug. 23.5692 TT         Peri. = 157.3575
