This time-lapse video of Sunday’s solar eclipse highlights the Sun’s outer layers:
The photographer Cory Poole constructed the video by pasting together 700 photographs taken with a Coronado Solar Max 60 Double Stack telescope. According to Jason Kottke, Poole used a filter that only allows light from hydrogen atoms moving from the 2nd excited state to the 1st excited state. This allows Poole to highlight the chromosphere, the Sun’s lower atmosphere.

Very cool.
Link to thisThanks Michael and Cory, what a great idea!
Link to thisGreat video, however, the advertisement in the video window was for a site touting a book on the End-Time (end of the world prophesied by the Bible). Surely, this type of ad is inappropriate for a publication such as Scientific American. Do they not have any control over what ads appear on their web site.

Interesting observation effort. However, I noticed two image artifacts.
- there is a peculiar foreground feature near the center of the solar disk that remains fixed even as the background disk image jitters
- why the moon edge shows the same appearance as the solar chromosphere
The above must be explained and taken care of. thanks
