Close Approach of (143947) 2003 YQ117 - PMSchu - 2022-11-09

CNEOS predicts that this large NEO will make a close approach on 2022-Nov-12 18:45 ± < 00:01 UT at a distance of 0.10411 AU. H=15.4 magnitude, V Relative=20.15 km/sec, 'Rarity'=2 & Condition Code=0. This is a large NEO (2.2-5.0 km) with a well determined orbit.

Using MPC's elements for 2022 November 9 00:00 UT, ST4v predicts that this object will reach a peak brightness of 14.0 magnitude between November 20-24, a broad light curve. At minimum earth distance it will be in Centaurus in daylight moving at 16"/min.

Here's an Interactive Atlas chart showing the predicted path from November 12 to December 23 in Brisbane, Australia: [attachment=2567]

This is a southern hemisphere object in early November, but will become visible from the northern hemisphere later in the pass. 

Good hunting,

Although this big rock gets marginally better viewing circumstances (30° high due south) for SE Texas, it drifts into the faint magnitude 15s.

This NEO has now moved farther north & is visible from 40° N in Columba at an estimated 15 magnitude.
