Space Weather
This live feed is quite interesting because more than anything, its actually a prediction of future events. It is a prediction center for Space Weather, with very interesting measurements like Solar Wind Speed, Solar Wind Density and other Interplanetary components. I'm sure this is quite an interesting feed for me to extrapolate from, and I'd like to see where this goes.
Interesting enough, I found that the trend in both Speed and Density is a peak just after sunset, and exceptionally high levels all the way through the night till the sun comes out again. Maybe I could link the time of day to something in the future.
