Only in the fleeting darkness of a total solar eclipse is the light of the solar corona easily visible. Normally overwhelmed by the bright solar disk, the expansive corona, the sun's outer atmosphere, is an alluring sight. But the subtle details and extreme ranges in the corona's brightness, although discernible to the eye, are notoriously difficult to photograph.

I've used a couple of sites, but http://tinypic.com/ is the one I'ved used most recently.

The Baily's beads effect, or diamond ring effect, is a feature of total and annular solar eclipses. As the Moon covers the Sun during a solar eclipse, the rugged topography of the lunar limb allows beads of sunlight to shine through in some places while not in others..
Stunning! Thank you!

(12,604 posts)For one thing, the corona was nearly half again as big as shown, and there was a very real sense of it rippling in the solar wind. It was much more distinct. My personal photos don't show the rays.
As for the "diamond ring" effect, that occurs as the moon moves from covering the Sun's disk, and sunlight streams through valleys on the moon's surface.
Temperatures dropped significantly, you could see stars, and animals went into their sleep mode.
Next to the aurora borealis, a solar eclipse is one of the most spectacular astronomical events. If you get the chance, put both of them on your bucket list.

(12,469 posts)Luckily, it was around 6 a.m. and I was on the highway leading to Cody. People were stopped along the highway and I realized I didn't need to be IN Cody to see the spectacle. So I joined the people on the side of the highway.
That was a good choice because the traffic jam out of Cody was reported to be a couple of hours duration.
I am looking forward to the next North America eclipse in 2024.

(12,604 posts)We had driven from Palm Springs to Denver to see my sister, then used Google Earth to choose the exact location with the longest duration. Apparently several others had the same idea, because there were about 20 of us at this crossroads in the middle of nowhere.
