Discovery: [ IAUC 8765 ] comet P/2006 U3 = 1955 j1

R. Stoss, Astronomisches Rechen-Institut, Heidelberg, and Observatorio Astronomico de Mallorca, reports the recovery by J. L. Ortiz and A. Mora of P/2001 K1 (NEAT) on CCD images obtained with the 2.5-m Isaac Newton Telescope at La Palma, the object appearing asteroidal on 300-s R-band frames.  The astrometric observations provided below were measured by Stoss.  The indicated correction to the prediction on MPC 54169 is Delta(T) = -0.4 day.  The recovery positions appear to confirm the proposed identification of this comet with an object found by Stoss on Palomar Sky Survey plates from 1955; the 1955 astrometry falls within 15" of the position predicted from an orbit linking the 2001 and 2006 observations.

Recovery: [ IAUC 7629 ]

S. Pravdo, E. Helin and K. Lawrence, Jet Propulsion Laboratory, report the discovery of a comet by NEAT on CCD images taken with the 1.2-m reflector at Haleakala on May 20.5 and 21.4 UT.  M. Tichy and M. Kocer, Klet Observatory, note that the object had a 14" coma on May 21.9.  P. Prave  and P. Kusnirak, Ondrejov Observatory, report a 0'.3 coma and a 0'.8 tail in p.a. 290 deg on May 21.9.  T. B. Spahr, Minor Planet Center, has identified asteroidal observations of the object in LONEOS and LINEAR data back to Feb. 2.
