Click here for an explanation of pseudo-MPECs
TLEs are available for this object, and for most of the other objects listed on these pages. Note that, because of sparse data and unpredictable non-gravs, the TLEs are probably only good for a few months around the date of observation. I mostly just hope that they'll be good enough so that if the object is found again, it'll be identified and the orbit can be improved.

Display can be turned on/off in the 'advanced options' for ephemerides. When turning them on, you can select from various format choices (base-60, decimal, different precisions, etc.) Distances are in kilometers for distances under one million km (about 0.00668 AU), and in AUs for larger distances.
