Close Approach of 2024 JT3
CNEOS predicts that the newly discovered NEO, 2024 JT3, will make a close approach on 2024-May-09 09:34±00:14 UT at a distance of 0.00017 AU moving with V Relative=10.89 km/second, H=29.2 magnitude, diameter 3.9 m - 8.7 m and 'Rarity'=1. There is only a 0.37 day observation arc, the Condition Code=8 and the Earth MOID=0.000188866 AU. The solution date was 2024-May-08 09:12:03 PDT. The initial reported observation was by Mt. Lemmon Survey on 2024-05-08.

This discovery is so new that the MP wasn't included in the MPC's file of NEAs at Today's Epoch that I downloaded on 2024 May 8. MPC has elements available for the epoch 2024 Mar 31 0000 UT that SkyTools can download for 2024 JT3. Using MPC's elements for 2024 Mar 31 0000 UT, ST4v predicts that this NEO will reach a peak brightness of 13.5 magnitude on 2024 May 9 0600 EDT when the NEO will be traveling through Canes Venatici at 53.4 "/second in twilight as seen from Columbus, Ohio. This is one of the highest apparent motions that I've seen for a close approach, a real screamer, if you can find it. Unfortunately the orbit isn't well defined yet and there's not much time before the close approach.

Here's the Object Info dialog for this NEO:     

This is an object for which the orbital elements should be downloaded from the HORIZONS website near the time of observation and added to your MP database. Elements from the MPC are unlikely to provide positions accurate enough to find this fast-moving object.

Edit: This object will be easier to observe from western North America especially the US southwest.

Good Hunting,
