Comments on: Big Picture: The Sun http://blogs.discovermagazine.com/badastronomy/2008/10/13/big-picture-the-sun/ I am an astronomer, writer, and skeptic. I likes reality the way it is, and I aims to keep it that way. My real name is Phil Plait, and I run the Bad Astronomy blog.

(sorry, but I guess I'm still a geek :-) Questions and comments, as always, and I've actually got the time to post! If light at 171, 195 and 284 Angstroms best shows temps around 1M, 1.5M & 2M (Kelvin?), respectively (per <a href="http://www.boston.com/bigpicture/2008/10/the_sun.html#photo11" rel="nofollow">image #11</a>), why does the wavelength of 304 (presumably Angstroms, since it mentions UV light) in <a href="http://www.boston.com/bigpicture/2008/10/the_sun.html#photo19" rel="nofollow">image #19</a> show gasses at 60K degrees? Since this apparent (to me, anyway) discrepancy doesn't seem to be a unit issue (degrees C or F instead of Kelvin (not degrees :-)), is it because we're looking at ionized Helium (instead of the presumed Hydrogen)? The <a href="http://www.boston.com/bigpicture/2008/10/the_sun.html#photo3" rel="nofollow">CME blowing away the comet's tail</a> is so fascinating that I paused to watch for a few minutes before continuing. Of course, it took me a while to actually get through the entire page. Anyone know why the seismic waves in <a href="http://www.boston.com/bigpicture/2008/10/the_sun.html#photo8" rel="nofollow">image #8</a> accelerate? Thank you for the Ben Bova article link, Gary 7! BTW, I prefer Rankin to Kelvin. Degrees Rankin :-P - g^2 HAWESOME!!!1!!ONE!! (sorry, but I guess I’m still a geek :-)
