COMET C/2010 FB87 (WISE-GARRADD)
     An apparently asteroidal object (first discovery observation below)
reported by WISE was briefly on the NEOCP in early April and given the
designation 2010 FB87 (see MPS 320849).  An independent discovery reported
from the Siding Spring Survey (0.5-m Uppsala Schmidt) by G. J. Garradd (second
discovery observation below) as comaless but showing a possible extremely
faint 10" tail in p.a. 290 deg (on a stack of four images) was later placed on
the NEOCP.  Follow-up observations measured by S. Foglia, P. Miller and J.
Wood from a 30-s CCD exposure by Wood with the 2.0-m Faulkes Telescope South
(also at Siding Spring) on Apr. 23.6 UT shows a soft aspect with a 15" tail in
p.a. 140 deg.
