COMET C/2014 F3 (SHEPPARD-TRUJILLO)
     Scott S. Sheppard, Carnegie Institution for Science; and Chadwick A.
Trujillo, Gemini Observatory, report the discovery of a new comet in three
VR-band CCD exposures taken with the Blanco 4-m telescope at Cerro Tololo on
Mar. 26 and 28; in each 6-min exposure, the object has a distinct non-stellar
diffuse coma with no visible tail.  Sheppard obtained additional observations
of the comet with the 6.5-m Magellan telescope on May 23; in three 7-min
exposures, the comet shows an obvious diffuse coma.
