Minor Planet (52768) 1998 OR2 Close approach
#12
In that case it may be that any position predictions that you make 5 weeks in advance of the closest approach won't be sufficiently accurate. Then you'll need to get more current elements in a few weeks. I recall that for some events folks were updating the elements weeks & even days before the events in question.

If the MPCORB & ASTORB aren't being updated frequently enough, it will increase your error. It's predicted to be 10.9 mag at closest approach and moving 16.7"/min.

Hopefully you'll have good weather.
