COMET P/2014 U5 = P/2005 RV25 (LONEOS-CHRISTENSEN)
     M. Micheli reports the recovery of comet P/2005 RV25 (cf. IAUC 8620) on
images taken by D. Abreu (Oct. 23.0 UT; 1.0-m f/4.4 reflector, ESA Optical
Ground Station, Tenerife) and J. D. Armstrong (Nov. 17.3; 2.0-m f/10
reflector, "Faulkes Telescope North", at Haleakala), with the astrometry
tabulated below.
