This might be within reach of larger backyard telescopes for photometry. Assuming a typical albedo, the diameter is on the order of 130 m, so there's a chance...
Hi: I apologize for my early morning query. I went to the MPC Checker and can produce a list of known objects within a given FOV, R.A. and Decl., and so forth....
Hello Adam, with the MPC Checker you'll also get the motion of the objects. You can decide between the separate motion (default) and the total motion. The...
The way I do it is to view the area in question on TheSky (I'm sure other planetarium software will work too) with the entire MPCORB or ASTORB loaded. patrick...
