Further fluctuating slightly and going up again on day 56, reaching 12.22109817 on day 72. Then the rate increases more rapidly, see table below. From the latest elsets it seems to go up again till day 139 and then MM is increasing again. Perhaps Kurt Jonckheere can find some time to do a MM analyses, as he used to do in the past. I've requested historical TLE's from OIG for the period April 1st till present.
More accelerations are possible.
