On 3 December 2017, 20:54:51 UTC, PrimeGrid’s PPS Mega Prime Search project found the Mega Prime:
1065*2^3447906+1

The prime is 1,037,927 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 210th overall.

The discovery was made by Juan C. Toledo (Meithan West) of Mexico using an Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz with 8GB RAM, running Linux. This computer took about 1 hour 48 minutes to complete the primality test using LLR. Juan is a member of the UNAM – Universidad Nacional Autonoma de Mexico team.

The prime was verified on 3 December 2017, 22:23:34 UTC by Lucas Brown (LucasBrown) of the United States using an Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz with 64GB RAM, running Linux. This computer took about 48 minutes to complete the primality test using LLR. Lucas is a member of the XKCD team.

For more details, please see the official announcement.
