On 16 May 2016, 07:12:37 UTC, PrimeGrid’s PPS Mega Prime Search project found the Mega Prime:

373*2^3404702+1

The prime is 1,024,921 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 152nd overall.

The discovery was made by Seonghwan Kim (ext2097) of South Korea using an Intel(R) Xeon(R) CPU E3-1231 v3 @ 3.40GHz with 4GB RAM, running Linux. This computer took about 56 minutes to complete the primality test using LLR. Seonghwan is a member of the SETIKAH@KOREA team.

The prime was verified on 17 May 2016, 01:25:38 UTC, by Bob Bussard (RGB) of Canada using an Intel(R) Core(TM) i5-3230M CPU @ 2.60GHz with 8GB RAM, running Microsoft Windows 8.1. This computer took about 3 hours 39 minutes to complete the primality test using LLR.

For more details, please see the official announcement.

It is not. #72 on that list is not actually a prime that was discovered at PrimeGrid. I'm unsure of its origins and how it got into the database, but it was discovered elsewhere.
