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 orbital elements of 249P/LINEAR, as provided by the minor planet center, are:

            e (eccentricity)                : 0.8201480
            q (perihelion distance)         : 0.4967480
            i (inclination)                 : 8.39710
            Ω (Longitude of ascending node) : 239.17750
            ω (Argument of perihelion)      : 65.60700
            L (Longitude of perihelion)     : 304.55140
            B (Latitude of perihelion)      : 7.64282

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 (15.50 + 5 log[∆] + 10.00 log[r]), whereas the red curve is being recalculated every 6 hours based on the available COBS/MPC observations (currently 19.07 + 5 log[∆] + 10.00 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 1.00. (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.
