The Tracks of the Meyer Comets
in C2** (and ****here in
C3****)
**

The tracks are drawn for the 15th day of each month.

The tracks are running from red to blue to gray (from the bottom upwards).

The first gray number is at the perihelion of the orbit.

Numbers are drawn every 30 minutes.

The numbers give the velocities in pixel/hour for the C2 1024*1024 images.

**The elements used are the weighted means of the
elements of the 29 confirmed Meyer comets **(2002
Aug)**:**

**q = 0.0362, peri = 57.3, node = 72.6, incl = 72.4 deg
(L = 97.8, B = 53.3).**

**The weights are the lengths of the observation times
(last obs - first obs).**
