COMET P/2011 L5 (LINEAR)
     J. Scotti, Lunar and Planetary Laboratory, University of Arizona, reports
his recovery of comet P/2000 G1 (cf. IAUCs 7396, 7408) on images taken with the
Spacewatch 1.8-m f/2.7 reflector at Kitt Peak, with the available astrometry
given below.  The object is just slightly softer than stellar images nearby.
