CNEOS predicts that the Aten class NEO, 2010 WC, will make a close approach on 2024-Nov-21 01:26±<00:01 UT at a distance of 0.00494 AU moving with V Relative=9.11 km/sec, H=25.3 magnitude, diameter 23 m - 52 m and 'Rarity'=1. There is currently a 5110 day observation arc, the Condition Code=2 and the Earth MOID=0.00400079 AU. The solution date was 2024-Nov-12 03:12:01 PST. The initial reported observation was by Catalina Sky Survey on 2010-11-16. With H=25.3 this NEO is too small to make MPC's list of Potentially Hazardous Asteroids (PHAs). This approach is the closest between 1900 and 2179 and very close to the Earth MOID.
Using MPC's elements for 2024 Nov 12 0000 UT, ST4.1.11.14 Pro predicts that the close approach will occur (to the nearest hour) on 2024 Nov 20 at 2100 EST with the NEO 743.33 k km distant and 15.9 magnitude traveling through Andromeda at 158"/minute. Peak brightness of 15.3 magnitude is predicted around midnight of 2024 Nov 20 when the NEO will be ~1000k km distant moving from Taurus into Aries at ~85-90"/minute.
Here's the Object Info dialog for this object:
This approach will be close enough that parallax will affect the apparent positions of the NEO from different locations on earth. For the most accurate results observers should download their orbital elements from JPL's HORIZONS website for a time near their time of observation.
Good hunting,
