That station has now surpassed its all-time low record pressure of 895.1 mb set in 2016.

Re: Intense Extratropical Low near Antarctica
Is this the most intense extratropical cyclone ever recorded? I can't find any mention of an extratropical cyclone deeper than the Braer Storm, which was 'only' 914 mb. It might also be the case that in the past there were also cyclones like these near Antarctica, but that they just spawn in an area so remote that we never really cared/knew about them. Especially before the satellite era.
