COMET P/2008 C2 (TICHY)
     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.
