John, you can add asteroids one by one in 3.0 and 2.76 as well I think. This is a challenge because the fields don't all match directly.
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. CdC chugs away for a while to digest it but it works fine. I don't think the file can be used in 2.76 but I'm not positive. I can now see the occultation occur in CdC. Cool! Now if only 3.0 supported the animation support like 2.76 I could save a movie of the event :) Sander John Mahony wrote: > > > > --- Sander Pool <[EMAIL PROTECTED] > <mailto:sander%40tungstentech.com>> wrote: > > > > > I just came across an asteroid, (2025) Nortia which is not in the > > asteroid catalog that CdC uses by default.
