COMET P/2006 Y1 (KORLEVIC-JURIC)
E. J. Christensen reports his recovery of comet P/1999 DN_3
(cf. IAUC 7167) on CCD images obtained with the 1.5-m reflector at
Mt. Lemmon, with his astrometry provided below. On Dec. 16.4 UT,
60-s images obtained in average seeing showed a moderately
condensed 5" coma with a 15" tail in p.a. 270 degrees. Four
co-added 60-s images obtained the following night in poor seeing
confirm a faint 10" tail in p.a. 260 degrees.
