Close approach of 2022 TD

[PMSchu]

CNEOS predicts that the newly discovered NEO 2022 TD will make a close approach on 2022-Oct-06 03:53 ± 00:07 UT at a distance of 0.00249 AU. H=27.8 magnitude, Vrel=10.11 km/sec & 'Rarity'=0.

ST4v predicts that maximum brightness of 16.7 magnitude will occur on October 5 at 20:00 EDT when the MP will be moving through Cassiopeia at 300"/min. Minimum Re is predicted on October 6 at 00:00 when its brightness will have decreased to 17.2 magnitude. It will be moving through Cepheus at 342"/min. The moon will interfere unfortunately.

Here's an IA chart showing the predicted path on the night of October 5-6, 2022 as seen from Columbus, Ohio: [attachment=2533]

This NEO isn't well placed for the southern hemisphere.

Good hunting,

Thanks Phil, La Nina is still active in SE Qld, so no clear nights down under for a while.

Cheers

There are a couple of big one coming up in November.

Phil, you talking 2022 RM4 on the 1st of November and 2005 LW3 near Thanksgiving? Have not run RM4 yet but indicated bright magnitude is intriguing.

TD really caught my attention at a speed of near 6 arc minutes per minute. It was very well placed for me (48° high & due north) but in massive moon glow. Went dim quickly as the sun angle plummeted and altitude crashed.

Looks as if RM4 should catch the attention of Dennis as it will be bright (in 14s) and moving ~2'/min. Looks like Dennis is 15 hours ahead of me so altitude may be the issue.

BMD, yes those are the 2 that I was referring to. I've been watching the CNEOS data for 2022 RM4 as they refine the time of the close approach. The error's now down to ±39 minutes from what it was on September 16 when it was ± 2 days, 21 hours, 7 minutes. Quite an improvement.

There's also (177614) 2004 HK33 that's currently estimated to be 15.7 magnitude in Octans heading for a peak brightness of 15.2 magnitude at 0.11 AU in Eridanus on October 13 at 2300 EDT. Predicted motion is 8.26"/min.  I need to make a post for this one, it's almost here.

There's also 2009 HV58 which is a southern hemisphere object estimated to reach 16.5 magnitude in Octans on November 30. Its approach has a 'Rarity' of 2.

There have been quite a few NEOs discovered recently.
