COMET P/2013 X2 = P/2008 A2 (LINEAR)
H. Sato, Tokyo, Japan reports his recovery of comet P/2008 A2 (cf. IAUC
8912) on luminance-filtered CCD exposures taken with iTelescope 0.51-m and
0.43-m astrographs near Mayhill, NM, U.S.A. (astrometry tabulated below), the
object appearing stellar on both nights in numerous stacked 60-s exposures.
