C/2013 F1 Boattini
more info
Comet C/2013 F1 was discovered on 23 March 2013 by Andrea Boattini during Catalina Sky Survey, that is about 3.5 months after its perihelion passage. Next, it was followed more than two months until June 3. Comet had its closest approach to the Earth on 5 April 2013 (1.64 au, 13 days after discovery).
GR solution given here is based on data spanning over 0.20 yr in the post perihelion leg of orbit in the range of heliocentric distances from 2.31 au to 2.88 au. Due to short data arc the NG orbit is not possible to obtain.
This is comet outside the Oort spike with semimajor axis of about 1900 au. Comet suffers notable planetary perturbations while passing through the planetary system and these perturbations lead to escape the comet from the planetary zone on a hyperbolic orbit (see future barycentric orbits).

Upper panel: Time distribution of positional observations with corresponding heliocentric (red curve) and geocentric (green curve) distance at which they were taken. The horizontal dotted line shows the perihelion distance for a given comet whereas vertical dotted line — the moment of perihelion passage.
Middle panel(s): O-C diagram for a given solution (sometimes in comparison to another solution available in CODE), where residuals in right ascension are shown using magenta dots and in declination by blue open circles.
Lowest panel: Relative weights for a given data set(s).
