Solar eclipse last Friday across central Asia

The solar eclipse last Friday across central Asia was captured by photog. Hartwig Luethen, in Kochenovo, Russia.( H/T Spaceweather.com )

The corona of our sun ( the white, gaseous fingers escaping ), seen only in photographs made during a total eclipse like this one, is hundreds of times hotter than the estimated surface of the sun, or about 2,000,000 degrees Celsius (about 3,600,000° Fahrenheit, but who's going to go out and read that thermometer!?).

There are many ideas to explain the extraordinary warmth of the Sun's corona. The leading theories fall into three categories: miniature solar flares, atmospheric waves, and electrical dissipation.

Or maybe they should think about re-estimating the temperature of the sun's surface~
