According to my copy of Guide9 (Pluto project) full moon occurred at 21 Jan 05:16:04 UTC.

And not just any full moon, but a Super Blood Werewolf Zombie Apocalypse full moon (or some such drivel spouted by all the TV stations). >Anyway, I wanted to know when the eclipse was at it's maximum. Most web sites >gave a time here as 23:12, some differed by several minutes. None gave the time to the second. That just won't do for a moon worshiping time-nut, will it? So, I tricked up a version of Lady Heather to do a screen dump when the difference of the sun and moon azimuth and elevation were at a (180 degree) minimum. Looks like it happened at 23:12:04 >Heather's sun position code (based on Grena's algorithm 5) is VERY accurate >(and quite simple). The moon position code is pretty good... a better version would require several thousand lines of code evaluating a zillion polynomials with hundreds of terms. >Anyway,, attached is a copy of the screen dump. Note the difference in the >sun/moon az/el values and also the calculated moon phase. >Does anybody know of a reliable source of the true time of the lunar eclipse >down to the second (or better)?
