* Major class X3.3 flare observed off the southeast limb at 21:30 UTC on 20 July.

The x-ray and radio signatures of this event suggest it was a probable
proton producing flare. However, no significant flux enhancements are
expected in the near-Earth space environment due to its present poor
location. X-ray fluence with this event was modestly respectable at near
0.75 Joules.

I think the proton flux tends to dampen quakes - but the proton numbers from this flare haven't changed. At 21:30 the sun should have been over about Hawaii, polynesia, east pacific rise, and The African rift zone area would have been sub-solar - I wonder if Volcano Nyiragongo displayed any more activity (its been active quite recently) - I don't see any immediate affect on the Live Seismocams from around the world.

It also takes a few days before the activity gets rocking.

I am contemplating doing some numbers games with various solar data and earthquakes - first I think something along the lines of a 5 year set of data - I guess it depends on how much solar data is available - but I think we need to correlate flares, electron flux, proton storms and ? along with the quakes and see if there is any trend.

Did you ever see Lowell's article posted on this site? He goes into some of the details - Review paper on Electrical/EQ Lights/ etc. - I would like to post this as an article on the site and have reformatted it and am just waiting on Lowell's permission to do so.

Its quite a task to analyze the solar/quake connection - I have another major project at hand I must complete before 8/19 - but I'm looking at it -

Someone else on another list I'm on came up with some numbers like earthquakes of 6+ occur 3 times as much after a solar flare as when no solar flare... I just don't know how well their data was put together.
