This was discovered today (March 10) running pmfs on my HPE Superdome X system. Interesting tidbit: this is the first factor discovered with n-m > 3 since Maximilian Pacher's factor of F3850 in Aug 2015.
Congrats! Maybe I'll get so lucky with one of my ranges.

There's an error at http://www.fermatsearch.org/factors/faclist.php :

The order of 45280 and 45278 is reversed.

Also the recent factor of F63480 from March is not yet included.

Thank you for the head-up. The site should be updated now.

Nice!

I found these for my current reservation. I have completed to n=269e6 and k=10499. About three weeks to finish that reservation.

218744235*2^10238+1 is a Factor of xGF(10235,5,3)!!!!
154520349*2^10365+1 is a Factor of xGF(10363,10,9)!!!!

Although I haven't finished the range, I found this:

1488947679*2^5201+1 is a Factor of F5199!!!!

I believe this is my first official Fermat factor.
