Az oroszok már a spájzban vannak! Idén ez már a harmadik orosz felfedezésű
üstökös, sőt, a C/2011 Q4 (SWAN) egyik felfedezője is orosz amatőrcsillagász
volt.

COMET P/2011 R3 (NOVICHONOK)
     Artyom Novichonok reports his discovery of a new comet (discovery
observation tabulated below) on six images taken during Sept. 7.02-7.05 UT
using a 0.4-m "Jigit" telescope at the TAU station of the Ka-Dar Observatory
(located near Nizhniy Arkhyz, Russia), with the object showing a small,
condensed coma of diameter 12" and an obvious tail 0´.6 long in p.a. 261 deg.
After posting on the Minor Planet Center´s NEOCP webpage, other CCD
astrometrists have also noted cometary appearance in this object.  N. Howes,
G. Sostero, and E. Guido stacked six 60-s R-band exposures taken on Sept. 8.4
with the the 2.0-m f/10 "Faulkes Telescope North" at Haleakala, which show a
sharp central condensation in a coma that is nearly 4" in diameter, elongated
toward the southwest, with a broad tail at least 7" long toward p.a. 252 deg.
G. Hug (Scranton, KS, U.S.A.; 0.56-m reflector) reports a well-defined narrow
tail extending about 1´ in p.a. 270 deg on his images from Sept. 8.4 and 9.3.
T. H. Bressi used the Spacewatch 1.8-m f/2.7 reflector on Sept. 9.3 to find
a tail 11" long in p.a. 5 deg.
