RE: [APML] The Atmosphere of Venus

Hi Chris,

Thank you.

Any claim like this should be open to challenge, and I welcome that.  If it 
was from refractive fringing, I don't know how it could come at that exact 
location though.

Here are other images that claim to show the atmosphere (in the same location):

Does anybody know of any more?

Jerry
