COMET P/2012 K2 = P/2005 K3 (McNAUGHT)
[Editor's note: the following text replaces that on CBET 3113.]
Martin Masek has reported astrometry (tabulated below), obtained remotely
with a 0.3-m f/10 reflector located near Malargue, Argentina, of what appears
to be a recovery of comet P/2005 K3 (cf. IAUC 8535), with nothing stated about
the object's appearance. The May 18 observations were reported first, and he
identified the May 15 data later.

G. V. Williams has confirmed the recovery of this comet with Delta(T) = -0.201
day from the prediction by S. Nakano in the *2011/2012 Comet Handbook*.
Orbital elements by Williams linking the two apparitions (cf. MPEC 2012-K37):
Epoch = 2012 Sept.30.0 TT
T = 2012 Sept.12.52304 TT Peri. = 15.69505
e = 0.5934966 Node = 351.96161 2000.0
q = 1.4971347 AU Incl. = 15.73559
a = 3.6829574 AU n = 0.13944695 P = 7.07 years
