Interesting....

And it turns out day 265 set an all time record, and then day 266 (Sept 22nd) broke that record. Days 265 through 270 are now the 6 highest Antarctic Sea Ice Extent’s of all time (in the satellite record)!

The only caveat that I would have is to see if the Nimbus images of the 1960's finds a larger extent.  I hate that the "official" records only go back to 1979, which is a crock.
