Yes they do, last time I used it anyway (in v2.76) (and you can add up to 100 at a time from the MPC- just change the downloaded file name from the MPC to asteroides.dat to replace CDC's existing asteroides.dat file). Remember to select "TheSky" format. I think V3.x uses a simpler format (MPC 1-line?) There was a format issue when the number of numbered asteroids went past 100,000 a few months back, so (for v2.76) make sure you have the "comet and asteroid download" update from CdC's download page. > In the mean time I found the file that contains many more (all?) > asteroids in the right format: > > http://cfa-www.harvard.edu/iau/MPCORB.html > > and specifically: > > ftp://cfa-ftp.harvard.edu/pub/MPCORB/MPCORB.ZIP > > This contains 130000 or so asteroids.

As I understand it, that's essentially the same as the ASTORB file someone else mentioned. It can be accessed in v2.76. -John > I can now see the occultation occur in CdC. Cool!
