Close approach of 2010 XC15
#4
The elements I'm using are for epoch 2022 Dec. 27.5UT and are only very slightly different for that date JPL vs MPC. Estimated positional difference is ~10" south for the JPL position. Mag 13.5 should be visible in my 13" if sky conditions allow.

I reran the ephem. Again, it's brightest and highest for me on the dark side of morning astronomical twilight of the 27th. But closest in daylight ~noon:13 @767,220Km moving 2.6'/min.
Paste these into your object editor:

Should work for your location in Ohio.

Here is a one degree wide FOV at 04cst on the 27th. The 6th mag star is HIP 66086 just 14' at pa288. Should make it crazy easy to locate the FOV.

   

The ephem position agrees with Horizons, etc.
