APOD: The Crown of the Sun (2010 Jul 21)

Image The Crown of the Sun

Explanation: During a total solar eclipse, the Sun's extensive outer atmosphere, or corona, is an inspirational sight. Subtle shades and shimmering features that engage the eye span a brightness range of over 10,000 to 1, making them notoriously difficult to capture in a single photograph. But this composite of 7 consecutive digital images over a range of exposure times comes close to revealing the crown of the Sun in all its glory. The telescopic views were recorded from the Isla de Pascua (Easter Island) during July 11's total solar eclipse and also show solar prominences extending just beyond the edge of the eclipsed sun. Remarkably, features on the dim, near side of the New Moon can also be made out, illuminated by sunlight reflected from a Full Earth.

Is that Mercury or Venus off to the left, or just some dust on the lens?

Remember that that area is the most light sensitive part of the image and should observe many faint stars.

Mercury or Venus would have to be within less than a day of (a close) conjunction
... so much less than a 1% a priori probability of being that close.

what caused the rings around the image ? i can see a pink hue then a thin green ring and a blue purple one beyond that.
Is this just a result of the photo or a feature of the corona?

New here. Hello all.

There is a cool video on YouTube (http://www.youtube.com/watch?v=zR6wVyBL ... r_embedded) of the eclipse as seen at sunset in Argentina.

Orin, go back to the original Apod picture and then click on "full Earth". Sometimes the pictures do not carry over through the links.

The link in the APOD caption at the top of this discussion is incorrect. There is a space in the middle that shouldn't be there, so the necessary parameters are not being passed to the simulator. Either use the link in the original APOD, or you can click here.

Are those curved lines on the top and bottom of the image the magnetic field's effect on the corona?
