Image of this new comet taken by Erik Bryssinck by use of 0.4-m f/3.8 telescope from BRIXIIS Observatory, Kruibeke, Belgium (B96 observatory)

Object was still mentioned on the PCCP of the minor planet center and observed to improve the ephemerides of this unknow object.

Later on 17 aug. this object assigned as comet C/2014 R4 (GIBBS) by CBET 3973 : 20140917 : COMET C/2014 R4 (GIBBS)

A. R. Gibbs reports his discovery of a comet on CCD images obtained with the Catalina Sky Survey's 0.68-m Schmidt telescope (discovery observations tabulated below); four co-added 30-s exposures show a diffuse coma 15" x 20" in size, elongated in the direction of motion and becoming a broad tail 20" long in p.a. 320 deg…..the w-band magnitudes were 15.7 and 17.9 as measured within circular apertures of radii 20".2 and 3".8, respectively.  E. Bryssinck (Kruibeke, Belgium; 0.4-m f/3.8 astrograph; Sept. 17.16) finds a diffuse coma of size 19" and a hint of a tail 28" long towards p.a. 244 degrees.      The available astrometry, the following elliptical orbital elements by G. V. Williams, and an ephemeris appear on MPEC 2014-S09.
