Discovery:

comet P/2001 F1 was discovered by E. F. Helin, S. Pravdo, and K. Lawrence, Jet Propulsion Laboratory, comet appears with a faint tail about 40" long toward the west-northwest and 20-the magnitude on CCD images taken with the NEAT 1.2-m reflector at Haleakala .  Additional observations, together with orbital elements (T = 2001 Jan. 21, q = 4.3 AU, i = 19 deg, P = 15.4 yr) by B. G. Marsden, are given on MPEC 2001-F51.  The object appears diffuse on Mar. 28.5 UT CCD images taken by G. J. Garradd, Loomberah, N.S.W. (0.45-m f/5.4 reflector).  CCD observations by M. Tichy and M. Kocer at Klet (0.57-m f/5.2 reflector) on Mar. 29.0 show a diffuse 10" coma.  P. G. Comba, Prescott, AZ, reports that CCD images taken with a 0.46-m f/4.5 reflector on Mar. 29.3 show a tail in p.a. 285 deg. (IAUC 7604 )

Recovery:

The comet was independently recovered at the Piszkesteto Station of Konkoly Observatory on 2016 January 7.90 and at the European Space Agency's Optical Ground Station, Tenerife on January 10.10. [CBET 4237, MPEC 2016-A105, 2016 January 11] The indicated correction to the prediction by S. Nakano in the ICQ's 2014 Comet Handbook is Delta(T) = -0.36 day.
