Venus Transit - June 05, 2012


4:01 PM 4:07 PM 4:15 PM 4:22 PM
4:45 PM 5:05 PM 5:25 PM 5:45 PM
6:05 PM 6:25 PM 6:45 PM 7:05 PM
7:25 PM 7:47 PM

The above sequence shows the movement of Venus over the sun during this transit.  Except for 10 minutes or so, the transit was marred by some form of cloud cover.  For example, the image at 7:25 PM is not missing, rather the cloud cover was so heavy that the sun could not be imaged.  The end of the transit viewing came at 7:47 PM when sun disappeared behind some trees and a thick cloud bank.

The event timings for the transit were: First Contact - 4:05 PM, Second Contact - 4:22 PM, Greatest Transit 7:27 PM. Third and Forth Contacts would happen after sunset.  (All times are in MDT.)

The image above shows the black drop effect.  The disk of Venus is within the sun's limb, but a dark area linking the disk to the limb of the sun is seen.  This effect can limit the accuracy of Second Contact timings.

This is the last shot of the transit that I obtained.  Here the sun briefly appears between a cloud bank and tree branches.
