Electronic Telegram No. 4294 Central Bureau for Astronomical Telegrams Mailing address: Hoffman Lab 209; Harvard University; 20 Oxford St.; Cambridge, MA 02138; U.S.A. e-mail: cbatiau@eps.harvard.edu (alternate cbat@iau.org) URL http://www.cbat.eps.harvard.edu/index.html Prepared using the Tamkin Foundation Computer Network COMET C/2014 HU_195 M. Busch, Heppenheim, Germany, reported on July 5 a comet with a weak central condensation and a 10" coma (and no tail) that was found by the automatic TOTAS evaluation software written by himself from four images (in 1" seeing) taken by David Abreu with the 1.0-m f/4.4 reflector at the European Space Agency's Optical Ground Station, Tenerife, in the course of the Teide Observatory Tenerife Asteroid Survey (TOTAS); the observing run was organized by M. Micheli, E. Schwab, and Busch, while J. Linder (Durmersheim, Germany) confirmed the images and reported the cometary nature. Their astrometry is tabulated below: 2016 UT R.A. (2000) Decl. Mag. Observer July 5.05907 20 42 48.01 -19 12 07.9 20.3 Abreu 5.07076 20 42 47.77 -19 12 08.5 21.0 " 5.08245 20 42 47.60 -19 12 09.7 20.2 " 5.09414 20 42 47.41 -19 12 11.1 20.0 " After the comet was posted on the Minor Planet Center's PCCP webpage, other CCD astrometrists confirmed the cometary appearance. M. Micheli communicates that unfiltered 180-s exposures taken by F. Monteiro, H. Medeiros, D. Lazzaro, J. S. Silva, R. Souza, and T. Rodrigues (OASI Observatory, Nova Itacuruba, Brazil; 1.0-m f/7 reflector) on July 6.1 UT show a diffuse coma with a FWHM of about 3" (in seeing of about 2") with a faint tail about 5" long to the west of the nuclear condensation. H. Sato, Tokyo, Japan, notes that twenty stacked 60-s exposures taken with an iTelescope 0.43-m f/6.8 astrograph (+ luminance filter) near Mayhill, NM, USA, on July 6.3 show a moderately consensed coma 12" in diameter with a hint of tail 20" long toward p.a. 260 degrees; the w-band magnitude was 18.9 as measured within a circular aperture of radius 5". D. J. Tholen writes that images taken by Y. Ramanjooloo and himself with the 2.24-m University of Hawaii reflector atop Mauna Kea on July 6.5 UT show a fan-shaped tail extending to the west; he measured red mag 19.7-19.8. Once an orbit was computed using the 2016 observations over a few nights, one of G. V. William's automated routines at the Minor Planet Center made a linkage to an apparently asteroidal object observed on only two nights in 2014 (though the uncertain very-distant 2014 orbital elements and the 2016 elements were quite different), to which the MPC had then assigned the minor-planet designation 2014 HU_195 (published on MPO 322309); the 2014 object was found and reported by Frank Valdes via the Dark Energy Camera (DECam) mounted at the prime focus of the Blanco 4-m telescope at Cerro Tololo in the course of the "DECam NEO Survey", and the astrometry sent by Valdes is tabulated below: 2014 UT R.A.
