On 17 September 2017, 20:18:24 UTC, PrimeGrid’s Sierpinski/Riesel Base 5 Problem project eliminated k=301562 by finding the mega prime:

301562*5^2408646-1

The prime is 1,683,577 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 57th overall. 72 k's now remain in the Riesel Base 5 Problem.

The discovery was made by Håkan Lind (sangis43) of Sweden using an Intel(R) Core(TM) i7-5820K CPU @ 3.30GHz with 32 GB RAM running Microsoft Windows 7 Professional Edition. This computer took about 43 hours 57 minutes to complete the primality test using LLR. Håkan is a member of the Sicituradastra. Team.

For more details, please see the official announcement.

Double-checker information TBA.
