I'm wandering how to calculate a rough idea of the uncertainty in the position of a given asteroid. I've taken as expamle 2005 JG2 with U=2, Epoch = 2453800.5...

Yes, Google Earth can run with dial up, but not on a machine which does not support Open/GL (Graphics Libraries). So too bad for my old notebook. Around here...
I tried over two nights this week to get this asteroid - almost 'stationary' but very bright (16.2 mag). I failed to see anything that bright or moving ever so...
Must be an error in the predicted H (or apparant magnitude); the Lowell 'asteph' routine is showing current V = 20.8, not 16th. And the location in the very...

It looks like this is an unknown crater. On checking the The Earth Impact Database (http://www.unb.ca/passc/ImpactDatabase/) The only crater listed in the...

Hi Juan, "... According to the mcp the runoff in longitude for U=2 should be less than 19.6 arc secs per decade..." Yup. But that's the runoff in the mean...

Hi Raoul, I know that at least a few users of my software have run into this issue. For near-earth objects, even a hundred-day step can be too much, and you...
... Huh? New epochs for contributors of perturbed orbital elements are changed every 200 days. It makes no sense for MPCORB to be any different....
