Roger:

Of course.

The test is whether or not "above average" activity happens (to see if this hypothesis is of any value). Obviously, LW must have had some data which suggested that it was true.

Interesting that I don't recall you raising this point when LW first mentioned it.... Maybe you were busy elsewhere at the time(?).

Yes, it is a large area. The question remains: "Is it useful or not for prediction purposes ?".

Maybe you can modify one of your programs to calculate the expected odds of M5+ quakes in the region as defined above. Then we can see if activity spikes above the norm or not.

I think your qkring (4 band + probability calcs) program could be quickly modified by allowing the user to specify just the sub-solar meridian (and the program does the rest). OR even just specifying the time of the flare and letting the program find the sub-solar meridian....

What do you think ?
