During the extreme activity from 2000 through 2004, I looked at that particular chart often and quickly learned that it's great eye candy, but isn't helpful.

This is the image you need. In the first plot, you want white line to be nice and high, at least 20 or so. The red line is perhaps the most important. It needs to be solidly in negative territory, the longer and lower it goes, the better. If it's in positive territory, nothing will happen. Ideally, you want the orange line to be at least 10. The yellow line is the solar windspeed, which you can use to easily see when the blast arrives. Faster is always better, I like to see >700 before I get excited.



As it stands now, not much is going to happen.
