The orbital elements that I downloaded for 2022 NF altered some of the predictions. The CNEOS website now has the close approach occuring on July 7 at 1345 ±03 UT at a distance of 0.00059 AU, H=28.5, 'Rarity'=1.
Some of the predictions from ST4v have changed as well. Here's a revised IA chart showing the predicted path of 2022 NF on the morning of 2022 July 7 from Mesa Redonda Observatory: [attachment=2427]
Unfortunately it didn't get any brighter
, but it is moving even faster than initially predicted. At close approach it's moving through Ursa Minor at 25.2"/sec, although still in daylight 
!
Several more NEOs were added to the zoo, but none will be brighter than 17.7 magnitude when they pass by.
