On 25 February 2016, 02:26:37 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime:

43165206^131072+1

The prime is 1,000,753 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 15th for Generalized Fermat primes and 154th overall.

The discovery was made by Alen Kecic (Freezing) of Germany using an NVIDIA GeForce GTX 660 Ti in an Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz with 8GB RAM, running Windows 7 Professional. This GPU took 52 minutes to probable prime (PRP) test with GeneferOCL2. Alen is a member of the SETI.Germany team.

The prime was verified on 26 February 2016, 02:40:45 UTC by [CSF] Joris Degraide of France using an NVIDIA GeForce GTX 970M in an Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz with 16GB RAM, running Windows 7 Ultimate. This GPU took 48 minutes to probable prime (PRP) test with GeneferOCL2. [CSF] Joris Degraide is a member of the CRUNCHERS SANS FRONTIERES team.

For more details, please see the official announcement.
