This is a close up of a detail of the EGRESS movie. The image contrast has been changed to show the elusive ring outlining the disk of Venus. It is caused by sunlight being refracted towards us in the atmosphere of the planet. It has been described by some historical observers, though the reports are mixed with spurious light effects caused by imagination or inferior telescopes. Also here one notices the shivering due to 'seeing'.
Observed with the Swedish 1-m Solar Telescope (SST).
