from YFRT (link)

This is very much thanks to DB who emailed some data to me, regarding the YRFT post about the sun going Topless and Bottomless.

DB sent the following link: http://sohowww.nascom.nasa.gov/data/realtime/image-description.html

It shows how the EIT (Extreme ultraviolet Imaging Telescope) image of the sun changes, depending on the wavelength of light being viewed. Hare's a summary.

EIT 304 Angstroms: bright spots at 60-80,000 degrees (Kelvin) (red image)
EIT 171 Angstroms: bright spots at 1,000,000 degrees (Kelvin) (blue image)
EIT 195 Angstroms: bright spots at 1,500,000 degrees (Kelvin) (green image)
EIT 284 Angstroms: bright spots at 2,000,000 degrees (Kelvin) (yellow image)

Here are the images I just snipped tonight from that link, in the order I just listed (click any image to enlarge).

So as you go to higher and higher temperatures, the pole holes look bigger. But the top image, at lower temps., shows the whole disc is still visible.

Therefore, it appears that the sun has not yet gone topless and bottomless... as sexy as that might have been!
