New Comet: C/2015 F2 (POLONIA)
March 27, 2015
CBET nr. 4083, issued on 2015, March 26, announces the discovery of a comet (magnitude ~17) by R. Reszelewski, M. Kusiak, M. Gedek and M. Zolnowski on CCD images taken on 2015, March 23 with a remote-controlled 0.1-m f/5 astrograph of the Polonia Observatory at San Pedro de Atacama, Chile, in the course of their comet-search program. The new comet has been designated C/2015 F2 (POLONIA).
We performed follow-up measurements of this object, while it was still on the neocp. Stacking of 14 unfiltered exposures, 30 seconds each, obtained remotely on 2015, March 23.8 from Q62 (iTelescope network - Siding Spring) through a 0.43-m f/6.8 astrograph + CCD, shows that this object is a comet with ill-defined central condensation surrounded by diffuse irregular coma 15" in diameter.
M.P.E.C. 2015-F120 assigns the following preliminary parabolic orbital elements to comet C/2015 F2: T 2015 Apr. 28.77; e= 1.0; Peri. = 351.97; q = 1.21; Incl.= 28.87
