On January 25th at 23:30:26 UTC, the largest known prime number, 257,885,161-1, was discovered on Great Internet Mersenne Prime Search (GIMPS) volunteer Curtis Cooper's computer.

So this huge gap in GIMPS primes was from April 12th 2009 02:27 UTC to January 25th 2013 23:30:26 UTC, which is:

3 years 288 days 21h03m26s =
197.83963 weeks =
1384.87738 days =
33,237.05722 hours =
1,994,223.43333 minutes =
119,653,406 seconds

We made it below 200 weeks and just below 2,000,000 minutes = 120,000,000 seconds

That could go in the "Misleading Headlines" thread ... "because there are none larger than this one."

Wow, it appears that the GIMPS super computer still works

Good job everyone. That was a long prime drought...

I still keep a few machine's pipelines stuff with prime candidates.

I started GIMPS in 1999 with AT compatible Pentium MMX 233MHz machine. This machine is still in service today and has contributed over 30 P90 years and >140 Trial Factoring jobs over the last 14 years! It's primary mission now is a NAS for remote backups, but it manages to squeeze some TF into its dated pipeline

I will explain after the official announcement.

In the New Scientist report of the latest Mersenne prime find they were compared to diamonds. Some rough calculations show that $1,000,000 was spent on electricity to run GIMPS over the last four years. These are very precious diamonds indeed.
