C/2010 X1 :
2011 Oct. 21.00 UT: m1=10.2, Dia.=7', DC=1/,
Tail: 0.4 deg. in PA 310 deg, 20 cm SCT (77x).
[ The comet's remnant appears visually like a very
diffuse tail-like morphology, observable for 0.4 deg
along the major axis, showing two near-circular areas of
similar brightness with a slightly higher degree of condensation
and 7' of diameter. One of this areas, with geometric center
located approximately at R.A.=8h00m.5, Decl.=+28o26'.0
(Oct. 21.00 UT), was close to the ephemeris position.
The other area's center was located at R.A.=7h59m.5,
Decl.=+28o34'.5. The motion of both areas was followed
for 40 minutes, being consistent with the ephemeris.
Observation made before moonrise, from mountain location
with very good seeing, under slightly better conditions than
twelve days ago (Oct.9). Nearby field stars checked in DSS.
Altitude: 16 deg.].
