2021-Mar-06 01:15 at 0.11265113489653 au or 43.84 lunar distances (LD).
I observed it on December 26, 2020 from my observatory at H47 when it was near magnitude 19.

Apophis has brightened to near magnitude 17.5 according to today's ephemeris.
Apophis is currently located in the sky constellation of Crater.
I read today that the OSIRIS-REx mission is considering (99942) Apophis as a follow on target . The mission team plans to propose an extended mission to NASA in the summer of 2022.
Goldstone Radar is planning to observe it in the coming weeks of January 2021.
(99942) Apophis brightened and was recovered by several NEO sky surveys in December as part of a Planetary Defense exercise which is now complete. The IAWN Apophis exercise continues.
