     K. Sarneczky, Konkoly Observatory; and P. Szekely, University of Szeged,
report their recovery of comet P/2007 T6 (cf. IAUCs 8881, 8894) on unfiltered
CCD exposures taken with the 0.60-m Schmidt telescope at the Piszkesteto
Station of Konkoly Observatory (astrometry tabulated below).  On Sept. 1.1
and 2.1 UT, the comet appeared completely stellar in appearance in a fifteen
stacked 120-s exposures.
