Jeff, See this link for professional info about the atmosphere of Venus: http://antwrp.gsfc.nasa.gov/apod/ap040610.html Rick R. SAC From: Jeff Hopkins [mailto:phxjeff@xxxxxxxxxxx] Note: What I am amazed at is how right-between-the-eyes the effect was on the computer monitor. There was most obvious a simmering clear or near-clear ring around Venus. I'm surprised there has been little professional information about this and I recall no mention of it in an pre-transit documentation.
