COMET P/2009 B3 (VAN NESS)
G. Hug, Scranton, KS, U.S.A., reports his recovery of comet
P/2005 R2 (cf. IAUC 8597) on images obtained with the 0.56-m
reflector at his Sandlot Observatory. A very faint, straight,
narrow tail was observed extending at least 5'-6' in p.a. 300 deg.
The indicated correction to the prediction on MPC 62880 is Delta(T)
= -0.06 day.

linked orbital elements and an ephemeris, appear on MPEC 2009-C03.

COMET P/2009 B4 (LINEAR)
Hug also reports his recovery of P/2002 CW_134 (cf. IAUC 7858)
in images taken at 25 deg altitude; the comet did not appear
different from stellar images in the same exposures. The indicated
correction to prediction on MPC 56802 is Delta(T) = -0.32 day.
