Comet P/2014 G2 = P/2005 JQ_5 (Catalina)
Abstract
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. 2014 UT R.A. (2000) Decl. Mag.
