COMET P/2014 Q4 = P/2005 Q4 (LINEAR)
     K. Sarneczky, Szeged, Hungary, reports his recovery of comet P/2005 Q4
(cf. IAUC 8595) on CCD images obtained with a 0.60-m Schmidt telescope.  He
remarks that the object was stellar in appearance.  G. V. Williams was able
to identify additional observations of P/2005 Q4 taken with the 1.8-m
Ritchey-Chretien Pan-STARRS telescope earlier the same night.

The indicated correction to the prediction by G. V. Williams on MPC 75706 is
Delta(T) = -0.26 day.  The following linked orbital elements by Williams
are from 186 observations spanning 2005 Aug. 31-2014 Aug. 23 (mean residual
0".5); additional orbital elements and an ephemeris appear on MPEC 2014-Q39.
