Comment added at 17:49 UTC on July 31: The geomagnetic field has been quiet to minor storm today. A large filament (or perhaps prominence) eruption in the northeast quadrant started just before noon. A full halo CME was later observed in LASCO images. Earth will highly likely receive an impact sometime between late on August 2 and late on August 3. Active to major storm, perhaps with severe storming at high latitudes, can be be expected for 12-24 hours following the impact.

Hey Andy -

That wouldn't be Max Factor would it? The King of Cosmoetics and Par-fumes!

Solar X-Ray flux has calmed down a bit from July 30 onward. Only minor M1 - M2 class flares. Geomagnetic was off the chart (so to speak) at :

But that appears to be a graphing error, not Kp=9 stuff. Hold on, the X-Class flares have not visited us lately, and they have added a class beyond X. I wonder why?

Kp is back around 4 as I write this tome. No lite show tonight in CA....

Keep your eyes open.....But don't stare into the sun.

This week we're visiting and camping in northern Ontario. Yesterday I was talking to a local who happened to mention that this year appearances of the aurora have been scarcer than in any year he remembers.

How this correlates to the reported increase in solar activity I can't imagine.
