Hi Bill & all,

In preparing for this occasion, I rigged the probes.dat file in Guide to use JPL osculating elements of 2012 DA14.

Animation works fine, but generating a trail and ephemeris results in a not-so-useful outcome. Guide just grabs the element set for the initial time and use it for the duration. E.g. http://clayhole.com/obs/2012da14.jpg shows the result of using three different starting times.

I've seen this previously but can't remember if I made a fuss about it then. I hope this is fixable.

Kind regards,
Jari
