As of today CNEOS still has the close approach of 2018 YK2 listed as occurring at 2022-Dec-26 01:21 ± 4_13:23 UT. They're using elements for the epoch 2023 Feb 25 on the Small Body Database Lookup page for this NEO.
Using the MPC's elements for 2022 Dec 20 0000 UT, ST4v predicts the close approach (to the nearest hour) on Dec 22@0100 EST (0600 UT) at
772.2k km distant, 14.4 magnitude when it's moving through Lacerta at 223.7"/min.
It looks like this NEO hasn't been recovered yet as the time of close approach is very uncertain at ±4.5 days.
2010 XC15 still looks to be on track for its close approach on December 27.
