On 21 February 2016, 16:55:42 UTC, PrimeGrid’s PPS Mega Prime Search project found the Mega Prime:

387*2^3322763+1

The prime is 1,000,254 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 152nd overall.

The discovery was made by Sami Heikkilä (samuel7) of Finland using an Intel(R) Core(TM) i7-3930K CPU @ 3.20GHz with 16GB RAM, running Microsoft Windows 10. This computer took about 1 hour 6 minutes to complete the primality test using LLR. Sami is a member of the PrimeSearchTeam team.

The prime was verified on 24 February 2016, 15:14:59 UTC, by William Donovan (Williamd007) of the United States using an AMD FX(tm)-9590 Eight-Core Processor with 16GB RAM, running Microsoft Windows 10. This computer took about 2 hours 27 minutes to complete the primality test using LLR. William is a member of the The Knights Who Say Ni! team.

For more details, please see the official announcement.
