Close Approach of (436774) 2012 KY3
#1
CNEOS predicts that the large NEO (436774) 2012 KY3 will make a close approach on 2023-Apr-13 19:08 ± < 00:01 UT at a distance of 0.03198 AU with V Relative=17.55 km/sec, H=18.5 magnitude, a diameter 540 m - 1.2 km and 'Rarity'=2. The Condition Code=0 and the Earth MOID=0.0238409 AU. The orbit is well known.

Using MPC's elements for 2023 Apr 3 0000 UT, ST4v predicts that this NEO will reach a peak brightness of 14.2 magnitude on the evening of April 14/15 at 0.04 AU distance moving through Octans at ~30"/min below the horizon in Columbus, Ohio. The close approach (to the nearest hour) on 2023 Apr 13 at 1500 EDT, 15.3 magnitude and 0.03 AU distance occurs in Grus with the NEO moving at 44.9"/min still below the horizon, now in daylight. This is a southern hemisphere object, weather permitting.

Here's the Object Info dialog showing the data at close approach:     

Good hunting,
