JWST will be in a 6 month halo orbit around the Sun/Earth L2 point, which is located at the anti-solar point. Internet graphics give conflicting information on whether the skypath is clockwise or counterclockwise around this moving point.
This post Will the James Webb Space Telescope be visible from earth? says JWST, in halo orbit, will be observable from earth by dedicated amateurs and provides a link for generating an ephemeris.
Will the skypath be clockwise or counterclockwise with respect to the antisolar point? Will JWST display apparent retrograde motion, or just “slow down”?

which suggests it doesn't incorporate MCC-2 and allows predictions up to 2022-Feb-14 00:01. So it seems until the results of MCC-2 burn are known, an accurate ephemeris won't be possible. There is some info here on JWST orbit but says these are "representative" $\endgroup$
