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.

            ω (Argument of perihelion)      : 67.2732
            L (Longitude of perihelion)     : 117.0274
            B (Latitude of perihelion)      : 55.9015
            T (Time of perihelion passage)  : 2456648.4219
            P (Orbital period in years)     : > 9999.99

The lightcurve 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 lightcurves are shown: The gray curve is based on the absolute magnitide and slope parameter as provided by the minor planet center (7.00 + 5 log[∆] + 10.00 log[r]), whereas the red curve is being recalculated every 6 hours based on the available COBS/MPC observations (currently 7.14 + 5 log[∆] + 13.73 log[r]).
