On 13 December 2020, 16:07:34 UTC, PrimeGrid's Fermat Divisor Search found the Mega Prime:

45*2^7661004+1

The prime is 2,306,194 digits long and enters Chris Caldwell's “The Largest Known Primes Database” ranked 77th overall.

The discovery was made by Tim Terry (TimT) of the United States using an Intel(R) Xeon(R) CPU E5-2670 0 @ 2.60GHz with 32GB RAM, running Linux Fedora. This computer took about 1 hour, 10 minutes to complete the primality test using LLR2. Tim Terry is a member of the Aggie The Pew team.

For more details, please see the official announcement.
