Alan, all,

I'm not too sure about the contributions from the flares. They were not 
earth-directed, and NASA had been predicting the arrival of of a coronal 
hole flow on the 19th or 20th. Perhaps it was a "vector sum" kind of 
thing. This was the first good bump we've had in a while.

John, W1TAG
