Total extent drop -93.6k, it is eating into the CAB now as well (-38.2k). Here is a diff with the previous day.

Bright red/blue: loss/gain of extent (crossing the 15% concentration limit). Light red/blue:  concentration change more than 7%.

From that image, we should expect that the melt progress on Pacific side of the CAB will determine this years minimum.

You using a trailing average or single day for extent above, Wipneus?

I recommend to read the top post of this thread, where Wipneus explained his algorithm. The values are single day, although there is filtering of spurious ice and false coastal ice.

Wipneus, your graphs from the top post stopped updating about a week ago.

I am worried about Wipneus. His updates were like a clock from Switzerland. How can I look at the state of sea ice without his product? This feels so 2012...

Yeah I am sorely missing the Regional area and extent graphs
