Update for the week to December 24^th

The current 5 day trailing average is on 11,866,000km² while the 1 day extent is at 11,847,000km².

(All the following data is based on a trailing 5 day average)
The daily anomaly (compared to 81-10) is at -1,372,000km², an increase from -1,261,000km² last week. The anomaly compared to the 07, 11 and 12 average is at -645,000km², an increase from -397,000km² last week. We're currently lowest on record, the same as last week.

The average daily change over the last 7 days was +40.6k/day, compared to the long term average of +56.4k/day, and the 07, 11 and 12 average of +76.1k/day.
The average long term change over the next week is +44.2k/day, with the 07, 11, and 12 average being +61.2k/day.

The extent increase so far this December is the 2^nd largest on record. To achieve the largest increase, a gain of at least 100.5k/day is required (at least +44.8k/day with with single day values), while the smallest increase requires a loss of more than 102.5k/day (more than 139.8k/day with single day values) and an average increase requires a loss of 23.2k/day (loss of 25.8k/day with single day values).

The average daily change over the last 7 days was -20.1k/day, compared to the long term average of -40.7k/day, and the 07, 11 and 12 average of -44.2k/day.
The average long term change over the next week is -43.1k/day, with the 07, 11, and 12 average being -45.2k/day.

The extent loss so far this April is the 4^th smallest record. To achieve the largest loss, a drop of at least 898.5k/day is required (more than -4,457.1k/day with with single day values), while the smallest drop an increase of at least than 25.5k/day (at least 161.9k/day with single day values) and an average loss requires a drop of 385.2k/day (1,891.0k/day with single day values).
