Cbet nr. 3638, issued on 2013, August 26, announces chem comm the discovery of a new comet (discovery magnitude ~20.8) by professional survey F51 Pan-STARRS 1 (Haleakala) on CCD images obtained with 1.8-m Ritchey-Chretien on August 15, 2013. After posting on the Minor Planet Center's NEOCP webpage, other CCD astrometrists have commented chem comm on the object's cometary appearance. The new comet has been designated C/2013 P4 (PANSTARRS) . We performed follow-up measurements of this object, while it was still on the neocp. Stacking of 9 R-filtered exposures, 60-sec each, obtained remotely, from the Faulkes Telescope South (Siding Spring) on 2013, August 26.5, through a 2.0-m f/10.0 Ritchey-Chretien + CCD (operated by Las Cumbres Observatory Global Telescope Network), shows that this object is a comet: sharp central condensation surrounded by a coma about 15" in diameter elongated in PA 190.
M.P.E.C. 2013-Q34 assigns the following preliminary parabolic orbital elements to comet C/2013 P4: T 2015 June 23.59; e= 1.0; Peri. = 157.50; q = 4.40; Incl.= 4.33 by Ernesto Guido, Kris Rochowicz, Nick Howes
