JAXA ARCTIC SEA ICE EXTENT :- 8,257,831 km2(November 6, 2019)
- Extent gain on this day 112k, 44 k more than the average gain of 68 k,
- Extent gain in this freezing season to date is 4,294 k, 29 k (0.7%) MORE than the average gain to date of 4,265 k.
- Extent is 2nd lowest in the satellite record below 2016 (532 k lower),
- Extent is 393k less than 2018, and
- Extent is 7 k below 2012,
- Extent is 385 k (4.5%) less than the 2010's average,
- on average 43.3% of extent gain for the the season done, 126 days on average to go.
Projections.
Average remaining extent gain in the last 10 years from this date produces a maximum of 13.84 million km2, lowest in the satellite record by 0.04 million km2.

Ice Gain Outlook??
Extent gains show further signs of moderating, though still very much above average
Diminishing +ve SST anomalies.
A change:- GFS says Arctic temperature anomalies increasing from +1.1 to +2.5 celsius over the next 5 days, and (take with a bag of salt**) a flood of warmth to +5.9 by day 10. In the first 5 days basically a tale of 2 halves - Pacific half warm, Atlantic half cold.
Will these 14 days of very high gains continue?
Or will daily gains return to the average or even below?

** GFS has form on predicting sudden warming events after day 5 that somehow usually fail to materialise. But in late Feb 2018 it did happen.
