COMET P/2014 G2 = P/2005 JQ_5 (CATALINA)
M. Masek, Liberec, Czech Republic, reports the recovery of comet
P/2005 JQ_5 (cf. IAUC 8531) on CCD images taken with a 0.3-m f/10 reflector
(astrometry tabulated below). The comet shows central condensation in a faint
coma of diameter about 40", with no tail.

The indicated correction to the prediction by S. Nakano on MPC 75732 is
Delta(T) = -0.10 day. The comet was missed at its 2009 return to perihelion.
