C/2014 B1 Schwartz
more info
Comet C/2014 B1 was discovered on 28 January 2014 with Tenagra Observatory near Nogales (U.S.A.), that is about 3.8 yr before its perihelion passage. This comet was observed until the mid-April 2022.
Comet had its closest approach to the Earth on 23 February 2018 (8.613 au), about 5.5 months after its perihelion passage. Similar close approach to the Earth was at the previous opposition on 11 February 2017 (8.664 au).
Solution 'b5' given here is based on data spanning over 8.24 yr in a range of heliocentric distances: 11.97 au – 9.557 au (perihelion) – 13.19 au.
This Oort spike comet suffers extremely slight planetary perturbations during its passage through the planetary system and its semimajor axis will be almost unchanged after leaving the planetary zone (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).
