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.

            q (perihelion distance)         : 1.41671
            i (inclination)                 : 15.05211
            Ω (Longitude of ascending node) : 349.35516
            ω (Argument of perihelion)      : 18.38840
            L (Longitude of perihelion)     : 7.15310
            B (Latitude of perihelion)      : 4.69913

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 calculated from the original MPEC, or the latest values provided by the MPC (13.50 + 5 log[∆] + 10.00 log[r]), whereas the red curve is being recalculated every 6 hours based on the available COBS/MPC observations (currently 9.25 + 5 log[∆] + 27.60 log[r]).

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

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