Congrats!
An awesome finding.

Many thanks for you.
My previous the best result was 24523881623890845010007531389564120430998338703 (154,1 bits 47 digits) for [url=http://www.mersenne.org/report_exponent/?exp_lo=31051&exp_hi=&full=1] M31051[/url]

Just out of curiosity, what were the bounds used? It's funny that they do not show up in the report.

Isn't that what [i]Miszka[/i] just said?

oops, I thought that was a report of a new factor.

Right. But you won't find there the usual info about the bounds. That's why I asked.
It's not common to find a 47-digit factor with a 3e6 B1!

I found very rough prime factor of [URL="http://www.mersenne.org/report_exponent/?exp_lo=199453&exp_hi=&full=1&ecmhist=1"]M199453[/URL]: 703714563044693056037968277785991 (109.1 bits)
k (90.511 bits) = 5 × 352822250377127973025208083
(ECM curve 219, stage #1, B1=250000, B2=25000000)
