COMET P/2012 P2 = P/2005 V1 (BERNARDI)
     D. J. Tholen, University of Hawaii, reports the recovery of comet P/2005
V1 (cf. IAUC 8627) on CCD images taken with the 8.2-m Subaru reflector at
Mauna Kea by M. W. Buie, M. Micheli, M. Ishii, T. Fujiyoshi, and himself
(astrometry tabulated below); the object presumably showed a stellar
appearance.

The indicated correction to the prediction by G. V. Williams on MPC 79348 is
Delta(T) = -0.07 day.  The following linked orbital elements by Williams are
from 49 observations spanning 2005 Nov. 1-2012 Aug. 16 (mean residual 0".2):
