Sziasztok!

Közben kiderült, hogy az üstökös március 26-án már lefotózta egy koreai
pofa, így elég érdekes neve lett a 9 magnitúdó körüli kométának.

COMET C/2009 F6 (YI-SWAN)
      Further to IAUC 9034, H. Yamaoka, Kyushu University, informs
the Central Bureau that he received an e-mailed report on March 28
of the discovery by Dae-am Yi (Yeongwol-kun, Gangwon-do, Korea) of
a possible comet with a noticeable greenish coma of diameter about
1´ (discovery observation tabulated below) on two 60-s CCD
exposures taken about 80 seconds apart with a Canon 5D camera and a
90-mm f/2.8 camera lens.  Orbital calculations suggest that this
object is identical with C/2009 F6.

      Mar. 26.835      22 39 40     +49 49 08    12.5     Yi

The available precise astrometry, the following preliminary
parabolic orbital elements from the precise astrometry only, and an
ephemeris appear on MPEC 2009-G21.

      Further visual total-magnitude and coma-diameter estimates:
Apr. 6.16 UT, 8.1, 7´ (J. J. Gonzalez, Burgos, Spain, 25x100
binoculars); 6.91, 9.7, 2´ (V. Nevski, Vitebsk, Belarus, 0.30-m
reflector); 7.06, 8.5, 4´ (B. H. Granslo, Fjellhamar, Norway,
0.20-m reflector; moonlight); 7.09, 8.5, 4´ (M. Reszelski,
Szamotuly-Galowo, Poland, 15x70 binoculars).
      S. Korotkiy and T. Kryachko, Moscow, report that their
unfiltered CCD observations with a 30-cm telescope at Karachay-
Cherkessia, Russia, on Apr. 7.06 show a bright asymmetrical coma of
size 332" x 354" (major axis in p.a. 161 deg) with an asymmetrical
condensation of size 12".8 x 19".3 (major axis in p.a. 320 deg).
