CNEOS predicts that the newly discovered NEO 2022 WA will make a close approach on 2022-Nov-18 06:43 ± < 00:01 UT at a distance of 0.00334 AU. H=26.8 magnitude, V relative=16.21 km/sec, 'Rarity' = 0, Condition Code = 6. This MP was discovered at Mt. Lemmon Survey on 2022-11-16.
Using MPC's elements for November 17, 2022 00:00 UT, ST4v predicts that this MP will reach a peak brightness of 16.4 magnitude on November 17 at 2100 EST when the NEO will be moving through Andromeda at 318.5"/min at 571.2k km distance. Close approach (to the nearest hour) is predicted to occur on November 18 at 0200 EST (0700 UT) when 2022 WA at 17.0 magnitude will be moving through Cygnus at 398.0"/min, 501.5k km distant 16° above the horizon as seen from Columbus, Ohio. Unfortunately ST4v predicts that it will not be observable with a 13" telescope under those conditions.
Here's an Interactive Atlas chart showing the predicted position of 2022 WA on November 17-18 as seen from Columbus, Ohio: [attachment=2575]
Since this NEO will get very close, parallax will affect the predicted positions, so you'll need to make charts for your location to get accurate positions for this object. Not much warning for this one.
Good hunting.
