Sunspots Return
We're emerging from the longest, deepest sunspot drought since 1913 (we discussed its depths here) with the appearance of a robust group of sunspots over the weekend. Recently we discussed a possible explanation for the prolonged minimum. The Fox News article quotes observer Michael Buxton of Ocean Beach, Calif.: "This is the best sunspot I've seen in two years." jamie found a NASA site where you can generate a movie of the recent sunspot's movement — try selecting the first image type and bumping the resolution to 1024. The magnetic field lines are clearly visible.
"This is the best sunspot I've seen in two years."
There is a very strong negative correlation between sunspot activity and temperature on Earth.
Aha! So global warming is causing the sunspots to disappear!
