COMET P/2014 C1 (TOTAS)
     [Editor's note:  this text replaces that on CBET 3799 (additional
discovery details reported).]
     Matthias Busch, Heppenheim, Germany, reports the discovery of a comet
(discovery observations tabulated below) showing a coma and a tail 10"-15"
long in p.a. 280-290 deg in the course of the Teide Observatory Tenerife
Asteroid Survey (TOTAS).  Rafal Reszelewski (Swidwin, Poland), one of a score
of people working in evaluating images, was assigned to review the specific
images of this object after they were automatically flagged by Busch's
software, and Reszelewski was the first to note the object's cometary
appearance on CCD images taken by Pablo Ruiz with a 1.0-m f/4.4 reflector at
the European Space Agency's Optical Ground Station, Tenerife.  The survey
fields were planned by Busch after Detlef Koschny suggested in January that
TOTAS search closer to the sun; the discovery report and astrometry were
sent by Busch to the Central Bureau and the Minor Planet Center.

After the object was posted on the Minor Planet Center's NEOCP and PCCP
webpages, it has been found to show cometary appearance by CCD astrometrists
elsewhere.  H. Sato (Tokyo, Japan; using an iTelescope 0.51-m f/6.8 astrograph
+ broadband luminance filter at Siding Spring) reports that the object showed
a strongly condensed coma that was elongated westwards (6" x 12" in size) with
a fan-like tail 30" long towards p.a. 280 degrees on eight stacked 60-s
exposures taken on Feb. 1.74-1.75 UT; the magnitude as measured within a
circular aperture of radius 8".8 was 18.2.  Seventy-five co-added 20-s images
obtained by T. Linder and R. Holmes with a 0.41-m f/11 Ritchey-Chretien
telescope at Cerro Tololo on Feb. 2.4 (measured by Linder, Holmes, and K.
Baker) show an elongated coma of size 4" towards p.a. 100 degrees and 3"
towards p.a. 190 degrees with an apparent faint 0".5 tail along p.a. 90 deg.
     The available astrometry, the following preliminary elliptical orbital
elements by G. V. Williams, and an ephemeris appear on MPEC 2014-C11.
