The daily anomaly (compared to 81-10) is at -1,134,130km², an increase from -1,023,690km² last week. The anomaly compared to the 07, 11 and 12 average is at -487,120km², an increase from -215,650km² last week. We're currently lowest on record, up from 2^nd lowest last week.

 

 

The average daily change over the last 7 days was -15.3k/day, compared to the long term average of +0.4k/day, and the 07, 11 and 12 average of +20.6k/day.

The average long term change over the next week is +0.7k/day, with the 07, 11, and 12 average being -4.0k/day.

 

 

The change so far this March is the 7^th most negative on record. To achieve the largest recorded monthly increase, a daily gain of over +22.3k/day is required, while the largest loss requires a loss of at least 25.0k/day and an average requires a loss of -3.6k/day.
