Year Mn Day MM Mag Ref Scope Pwr coma DC tail p.a. Obs Site 2009 9 20.79 S 13.6 HS 40.0L 144 0.8 1/ YOS Kita-karuizawa, Gunma (I imagined that it could have already faded out. But unexpectedly, it is still visible visually. Diffuse and faint. Hidetaka Sato reported a large coma of 3.4 arcmin was detected by CCD observations on the same night. So I could see only the central part. I did not try to see it with a lower magnification. Using a lower magnification, maybe a large coma would be visible and the total magnitude would become brighter.) 2009 9 1.106 S 12.2 TA 31.0J 89 1.0 4/ BOU Lauwersoog 2009 8 31.18 S 12.3 TK 20.3T 133 0.7 6 GON Alto del Castro - Aralla, León (Significantly brighter than expected. Nearby field stars checked in DSS. Motion checked over a 20-min period. Mountain location, very clear sky. Astronomical twilight. Altitude: 16 deg.)
