Today's Met Office FAX chart (1200) shows a High south of Newfoundland with central pressure 1051 mb. Does anyone know if this is a record for an Atlantic High or if not, what the record is? It's certainly the highest I have seen.

I thought meteorologically speaking, Greenland was ringfenced, and
anything appearing in synoptics should/could? be ignored as it is
usually just an artefact of "correcting" one set of readings on the
central highland , to MLSP.
The MetO model output of 24 Nov 2015 (00+144) and 2 other models of that
period showed 930mB just off Greenland, wow. It vanished just like
Scotch mist in later outputs, presumably as it was just this Greenland
artefact that got into the models.
