Cbet nr. 3901, issued on 2014, June 15, announces the discovery of a comet (~ magnitude 16.5) by the Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) team on images taken with the NEOWISE satellite on 2014, June 07.4. The new comet has been designated P/2014 L2 (NEOWISE).

Extract:

Rachel A. Stevenson, Jet Propulsion Laboratory, reports the discovery of a comet by the Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) team on images taken with the NEOWISE satellite …

After the object was posted on the Minor Planet Center's NEOCP and PCCP webpages, numerous other ground-based CCD astrometrists have also commented on the object's cometary appearance....   Thirtheen co-added unfiltered 60-s images taken by E. Bryssinck (Kruibeke, Belgium; 0.4-m f/3.8 astrograph) on June 12.08 reveal a coma of size 11" x 14" and a hint of a tail about 27" long towards p.a. 231 degrees; twenty co-added 120-s images taken on June 15.07 with a Bessel R filter show a coma of size 14" x 19" (magnitude 15.9 in an aperture of size 14"), elongated towards p.a. 289 degrees with a hint of a tail 21" long in p.a. 247 degrees.  S. Foglia reports that forty stacked 10-s .....
