CNEOS predicts that this large NEO will make a close approach on 2023-Feb-25 06:11 ± <00:01 UT at a distance of 0.12273 AU. H=18.1 magnitude, V relative=18.11 km/sec, 'Rarity'=1 & Condition Code=0. This is a large object, 360m - 1.4 km so it's already 16.1 magnitude according to ST4v despite still being 0.1 AU distant. I thought that it might be interesting to keep an eye on it as it approaches.
Using MPC's orbital elements for the epoch 2023 February 16 00:00 UT, ST4v predicts that this NEO will reach a maximum brightness of 16.1 magnitude on February 21 traveling in Centaurus at ~10"/min. The light curve is very wide, so the magnitude doesn't change much over several days near the maximum. This NEO is best visible from the southern hemisphere or below 30° N.
Here's an Interactive Atlas chart showing the predicted path of this NEO from 2023 February 17 - 27 for Brisbane, Australia:
Note that the times shown in the OI dialog Notes are EST.
Good hunting,
