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)         : 0.99888
            i (inclination)                 : 10.41630
            Ω (Longitude of ascending node) : 190.95570
            ω (Argument of perihelion)      : 343.34110
            L (Longitude of perihelion)     : 174.55647

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. The lightcurve is based on the absolute magnitide and slope parameter as calculated from the original MPEC, or the latest values provided by the minor planet center. (17.50 + 5 log[∆] + 10.00 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 shows the short-term path of the comet in a field of view that is optimized for (~10x50) binoculars and finderscopes.
A more printer-friendly version of the same chart can be found further down this page as well.

The following chart shows the current location of the comet in a smaller, upside-down telescopic field of view.
