The interactive orbit chart above shows the comet's path through the solar system and its position at the given date. Green and blue lines are shown perpendicular to the ecliptic plane: Green if the path is above the ecliptic plane, blue if it is below. (Left-click and drag to rotate the view; Right-click and drag to move the view; Use scroll wheel to zoom in our out.)

The orbital elements of A/2019 C1, as provided by the minor planet center, are:

            e (eccentricity)                : 0.9922276
            q (perihelion distance)         : 6.58100
            i (inclination)                 : 36.01700
            Ω (Longitude of ascending node) : 212.39452
            ω (Argument of perihelion)      : 319.20300
            L (Longitude of perihelion)     : 177.47562
            B (Latitude of perihelion)      : -22.59436
            T (Time of perihelion passage)  : 2458975.34259
            P (Orbital period in years)     : > 9999.99

The light curve chart below shows the estimated development of the comet's magnitude. Blue and black dots are visual and photometric CCD observations respectively from COBS or the MPC. Two light curves are shown: The gray curve indicates the expected brightness if this object is a comet (6.60 + 5 log[∆] + 10.00 log[r]), whereas the red curve indicates the expected lightcurve for an asteroid (H=10.40; G=.15).


The all-sky chart below shows the path of the comet over the same period as the light curve. The comet's current position is marked yellow.





The following chart shows the short-term path of the comet in a field of view that is optimized for (~10x50) binoculars and finderscopes.
