Close Approach of 2024 NS1

[PMSchu]

CNEOS predicts that the recently discovered Amor class NEO, 2024 NS1, will make a close approach on 2024-Aug-02 00:13±01:02 UT at a distance of 0.01351 AU moving with V Relative=7.56 km/sec, H=24.2 magnitude, diameter 38 m - 86 m and 'Rarity'=1. There is a 10 day observation arc, the Condition Code=8 and the Earth MOID=0.0113268 AU. The solution date was 2024-Jul-16 05:48:48 PDT. The initial reported observation was by Pan-STARRS 2, Haleakala on 2024-07-03. The orbit is still uncertain with the Condition Code=8 and 1 hour uncertainty of close approach time.

Using MPC's elements for the epoch 2024 Jul 19 0000 UT, ST4.1.11.10 Visual predicts that this MP will reach a peak brightness of 16.3 magnitude at close approach in Sagittarius when it will be below the horizon and still in daylight from Columbus, Ohio. This MP will be best observed from the southern hemisphere.

I'll update the information for this MP after the orbit has been better refined.

CNEOS has refined the orbit for 2024 NS1. The close approach is predicted on 2024-Aug-02 00:05±<00:01 UT at a distance of 0.01353 AU moving with V Relative=7.58 km/sec, H=24.3 magnitude, diameter 36 m - 81 m and 'Rarity'=1. There is a 24 day observation arc, the Condition Code=7 and the Earth MOID=0.0117298 AU. The solution date was 2024-Jul-27 06:20:57 PDT. This is an Amor class object.

Using MPC's orbital elements for the epoch 2024 Jul 27 0000 UT, ST4.1.11.10 Visual predicts that this NEO will reach a peak brightness of 16.4 magmitude on the night of August 1-2 when it will be traveling through Corona Australis at 45"/minute near the southern horizon in Columbus, Ohio. Close approach is predicted (to the nearest hour) on 2024 Aug 1 at 2000 EDT when the MP will be 16.4 magnitude in Sagittarius traveling at ~46"/minute in daylight and below the horizon in Columbus, Ohio. This NEO will be best visible from the southern hemisphere.
