Please be aware that cometary behaviour is difficult to predict by nature. Predictions on this page are based on standard models and the latest observations available to me, and will gradually improve with time. The ability of comets to either disappoint or pleasantly surprise us, is one of many things that make them so interesting.

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 light curve is estimated based on previous apparitions. (10.00 + 5 log[∆] + 8.75 log[r]). The additional green curve shows the effect of forward scattering, occurring when the comet is between the earth and the sun, for a gas-to-dust light ratio δ90 of 0.30. (See Marcus 2007)

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.
