CNEOS predicts that the NEO 2019 OR1 will make a close approach on 2022-Nov-21 02:28 ± < 00:01 UT at a distance of 0.04625 AU. H=20.8 magnitude, V relative=13.38 km/sec, 'Rarity'=1 & Condition Code=1. The size is estimated to be 180-410 m so it's 16.6 magnitude according to ST4v at 0.06 AU distant on November 16.
Using MPC's orbital elements for the epoch 2022 November 16 00:00 UT, ST4v predicts that this NEO will reach a maximum brightness of 16.5 magnitude on November 17 at 21:00 EST traveling through Pegasus at 19.5"/min. The minimum distance of 0.05 AU is predicted to occur on November 21 at 21:00 EST when it will be moving through Pisces at 16.8 magnitude and 24.2"/min. Older elements used to calculate the ephemeris in September indicated that this NEO would attain a peak brightness of 16.2 magnitude as indicated in the top portion of the Object Information dialog shown below, but the newer elements indicated otherwise. Consequently this object was downgraded from 4 stars to 3. This NEO passed very close to M 31 on the evening of November 14 when the predicted magnitude was 16.8.
Here's an Interactive Atlas chart showing the predicted path of this NEO from 2022 November 16-19 for Columbus, Ohio: [attachment=2574]
