An explanation of the orbital elements is available.

These orbital elements are also available in forms suitable for loading into a number of popular planetarium-type software programs.

Ephemeris

The following ephemeris is at intervals of five days. A daily ephemeris covering the same time interval is also available.

Personalized ephemerides for this (and other) objects may be generated using the Minor Planet & Comet Ephemeris Service.

Recent magnitude estimates for this comet (as reported to the ICQ) may be available.

Date TT R. A. (2000) Decl. Delta r Elong. Phase m1 m2

WARNING!

This comet gets close to the sun during the period covered in the ephemeris below. Observers are warned to be wary of observing comets near the sun. NEVER point any kind of optical instrument at the sun--instant blindness will be the probable result.
