C/2013 V1 Boattini
more info
Comet C/2013 V1 was discovered on 4 November 2013 by Andrea Boattini during Catalina Sky Survey, that is almost half a year before its perihelion passage, and was followed until 19 January 2015. C/2013 V1 had close approaches to the Earth on 23 December 2013 (1.47 au, about 1.5 month after the discovery).
This is a comet with NG effects strongly manifested in positional data fitting. Solutions 'a5' and 'n5' (preferred) are based on data spanning over 1.2 yr in a range of heliocentric distances: 2.70 au – 1.661 au (perihelion) – 3.69 au. GR solution 'ba' differ from 'a5' in the method of data weighting, silimarly the pair of NG solutions 'bn' and 'n5'.
This Oort spike comet suffers moderate planetary perturbations while passing through the planetary system; these perturbations lead to escape the comet from the planetary zone on a hyperbolic orbit (see future barycentric orbits) for all orbits given here.

The horizontal dotted line shows the perihelion distance for a given comet whereas vertical dotted line — the moment of perihelion passage.
