Q: Will the transit of Venus in a few weeks, be visible at Mars?
Could Oppy (or orbiters) resolve it ??? -------------------- CLA CLL

@jamescanvin: I considered that for a moment myself, but the time for the transit is 15,09 to 21,28 with sunset at 20,48. I thought that black part of the graph is when the transit is not visible from that location. So its too late of the day for that - or am I missing something?

I thought that black part of the graph is when the transit is not visible from that location. So its too late of the day for that - or am I missing something? Yes, but the crazy zig-zag bit is before the transit. The 'star' on the image is the position of Venus (off the disk) at the time shown in the upper right and is handily just before it executes the weird bit. This is 13:52 local (-7 from GMT) however -134.7 longitude is very close to 9 hours behind GMT (9*15 = 135) so the sun will pass through zenith (the site is also very close to the tropic line near midsummer to ensure this) at roughly 14:00, just the right time. @ddeerrff Correct -------------------- |
