Sehr eindrucksvoll und ich muß sagen: erinnert doch an McNaught...
Und hier auch noch mal der BB von A.Amorim:
2011 Dec 17.34 UT: m1= -2.9*, Dia= <1', DC=9, tail= 0.2 in P.A.240
10x50B...Alexandre Amorim(Florianopolis,Brazil)[comet alt. 4 deg, sun alt. -0.9 deg]
This estimate was made when Mercury was out of some clouds, and a comparison was possible. The tail was too faint (despite bright background). At 08:06 UT I detected the comet (alt. 3,5 deg).
At 08:19 UT (06:19 EBDT) the comet (alt. 6 deg) was visible between two clouds and Sun was rising.
