The object shows a strongly condensed coma of diameter 35" and a fan-like tail 65" long towards PA 290-343 degrees. 2014 UT R.A. (2000) Decl. Mag.

Sato, Tokyo, Japan, communicates that six stacked 30-s images taken on Mar. 13.6 UT with an iTelescope 0.51-m f/6.8 astrograph show the object to have a strongly condensed coma of diameter 50" and a tail 3' long toward p.a. 15 degrees; the luminance-filtered magnitude (radius 26".3) was 12.4. M. Urbanik, Cadca, Slovak Republic, notes that eight stacked 30-s images taken with an iTelescope 0.32-m f/9.3 astrograph at Siding Spring on Mar. 13.6 show a coma 30" wide with a diffuse tail at least 2' long spanning p.a. 10-30 deg. The available astrometry yielded the following very preliminary parabolic orbital elements and ephemeris by Gareth Williams at the Minor Planet Centre: T = 2014 June 29.5244 TT Peri. = 349.1077 Node = 58.4814 2000.0 q = 0.606313 AU Incl. = 157.1941 Ephemeris: Date TT R.

They estimated the object then at magnitude 11.4v. They add that their positional measure produced end figures of RA 23.73s and Declination 06.7" differing from some quoted on CBAT and included on TA E-Circular 2989. Editor: We would welcome further positional measures. The image by Denis Buczynski and Rob McNaught to aid identification has been included in the March issue of 'The Astronomer' due for publication on or about March 20. Guy M Hurst
