COMET P/2008 T5 (NEAT)
K. Kadota, Ageo, Saitama-ken, Japan, reports his recovery of
comet P/2001 J1 (cf. IAUCs 7623, 7625, 7635), showing a central
condensation, no tail, and coma diameter 0'.5-0'.6 on CCD images
obtained with a 0.25-m f/6 reflector. Confirming observations were
also made by H. Abe (Yatsuka-cho, Shimane-ken, Japan, 0.26-m
reflector).
