86M first test milestone; on to 87!
 

Nov 8 2019 last exponent is done.

87M looks iffy for 2019; there's an exponent projected to complete Dec 17, and many due to expire soon. Aurashift has 15 expiring today, many of which show more than 50% done.

49M DC is 2 away; the projection is one expires today and the other completes tomorrow.

last exponent to 49M DC milestone is stuck
 

Sitting at 71.1% for days. [url]https://www.mersenne.org/assignments/?exp_lo=48641447&exp_hi=49000000&execm=1&exp1=1&extf=1&exfirst=1[/url]

It looks like, with the typical Festivus miracle, we will pass the 87million milestone by the end of the year. Ideally we will also increment the known MP's by one as well.

FYI, 86939693 is on a colab instance of mprime, PrimeNet connected.

Re finding and verifying Mp52*, is George on holiday vacation yet? The last two were when he was traveling on vacation, as I recall.

* indicates provisional ranking, since double checking has not completed to Mp48* yet.

November through January, part of the heating season in the northern hemisphere, 1/4 of the year, accounts for the majority of finds to date, at 9 out of 17. Some participants are known to substantially augment home heating with Mersenne computations.

One to go, to the 87M tested milestone, expected done 2019-12-28. [url]https://www.mersenne.org/M86865047[/url]

11 months ago, in a post [URL="https://www.mersenneforum.org/showpost.php?p=478252&postcount=2759"]HERE[/URL] on Jan 24 2018, the Classic report had less the [B]9999[/B] remaining second tests for the exponents up to 50 million.

Yesterday it went under [B]999[/B] for the first time
So I'm guessing 2-3 months for the important 50 million completion to be reached.
