COMET P/2012 B2 (LINEAR)
H. Sato reports the recovery of comet P/2003 HT_15 (cf. IAUC 8156)
on CCD images taken by T. Seki, S. Shimomoto, and himself with a 0.70-m
f/7 reflector at Geisei, Japan (astrometry tabulated below). The comet
appears moderately concentrated with a coma of diameter 7" and no tail.
(though the coma seems extended slightly to the southwest on Jan. 26).

The indicated correction to the prediction by S. Nakano in the 2011/2012
Comet Handbook is Delta(T) = +0.28 day. The following orbital elements by
G. V. Williams are from 48 observations spanning 2003 Jan. 27-2012 Jan. 27:
Epoch = 2003 May 1.0 TT
T = 2003 Apr. 17.74527 TT Peri. = 124.05670
e = 0.4198836 Node = 81.47217 2000.0
q = 2.6715043 AU Incl. = 27.67042
a = 4.6051177 AU n = 0.09973394 P = 9.882 years
Epoch = 2013 Mar. 9.0 TT
T = 2013 Mar. 17.35282 TT Peri. = 124.11294
e = 0.4187859 Node = 81.44658 2000.0
q = 2.6899128 AU Incl. = 27.63669
a = 4.6280931 AU n = 0.09899219 P = 9.956 years
