Discovery: (IAUC 7515 )

An object found by Milos Tichy on images taken at Klet with J. Ticha and M. Kocer on Oct. 23 (discovery observation below), originally reported as asteroidal, was subsequently noted to be diffuse on Klet images taken during Oct. 28.9-29.2 UT; Tichy also noted a 10" coma on Oct. 29.8 images.  Images obtained on Nov. 1 by S. Sanchez and M. Blasco at Mallorca and by D. T. Durig at Sewanee also showed diffuseness.  MPEC 2000-V03 contains the available astrometry and orbital elements (T = 2000 Oct. 4.6 TT, i = 19.3

deg, q = 2.150 AU, P = 7.3 yr)

Recovery: ( CBET 8917 )

M. Tichy and J. Ticha, Klet Observatory, report their recovery of comet P/2000 U6 (cf. IAUC 7515) on CCD images obtained on Feb. 3

with the 1.06-m KLENOT Telescope, with Tichy's astrometric measures given below.  They subsequently identified earlier images from Jan. 11.
