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.

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. The gray curve is based on the absolute magnitude and slope parameter as calculated from the original MPEC, or the latest values provided by the MPC (7.50 + 5 log[∆] + 40.00 log[r]), whereas the red curve is being recalculated every 6 hours based on the available COBS/MPC observations (currently -.69 + 5 log[∆] + 40.00 log[r]).
