C/2019 M3 ATLAS
more info
Comet C/2019 M3 was discovered on 30 June 2019, about five months after its perihelion passage and was observed only to 25 October 2018.
Thus, the solution given here is based on post-perihelion data and span over 0.159 yr in a range of heliocentric distances from 3.09 au – to 3.93 au.
This comet seems to be Oort spike comet with a more tight future orbit than original orbit (see future barycentric orbit).

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).
