CNEOS predicts that the large NEO (363027)1998 ST27 will make a close approach on 2024-Oct-12 01:52±<00:01 UT at a distance of 0.02380 AU moving with V Relative=16.63 km/sec, H=19.6 magnitude, diameter 0.578±0.228 km and 'Rarity'=2. There is currently a 9503 day observation arc, the Condition Code=0 and the Earth MOID=0.00992384 AU. The solution date was 2024-Sep-30 06:23:23 PDT. This NEO was discovered at Socorro on 1998-09-24 by LINEAR. This large object is on MPC's list of Potentially Hazardous Asteroids (PHA).
Using MPC's elements for the epoch 2024 Sep 30 0000 UT, ST4.1.11.11 Visual Pro predicts that this NEO will reach a peak brightness of 13.0 magnitude on the early morning and evening of 2024 Oct 10 when the NEO will be traveling from Pegasus into Pisces at ~50"/minute. Close approach is predicted (to the nearest hour) on 2024 Oct 11 2200 EDT when the MP will be 0.02 AU distant traveling through Aquarius at 13.4 magnitude and 59"/minute. This large NEO should be brighter than 16th magnitude from October 3 (In Andromeda traveling ~4.3"/minute) to October 14 (In Telescopium traveling ~25.4"/minute in evening twilight near the horizon in Columbus, Ohio).
