Mercury Transit May 9, 2016 Uploaded 5/11/16

Above: Sunrise sequence, spanning roughly 15 minutes of time. You can see the sunspot above and to the left of the center of the Sun, and the planet Mercury is near the bottom of the disk.


Above: Zoom in on the center frame showing the details labeled.

Below - this is a series of images at prime focus with the Lunt and DMK51 camera in Hydrogen Alpha light showing the planet as a dark black dot.

Below: The limb of the sun showing prominences. Since the sun has to be greatly over exposed to show this faint detail, the pure white disk was blacked out like a total solar eclipse as to not be distracting.

Below: Combining both the prom shot and the disk shot shows the details at the same time.

Below: More full disk shots:








Below: Finally, the disk of the planet moves off the sun, but can be still be seen against the spicule layer on the limb. This layer extends beyond the normal edge of the sun and appears to give the sun a double edge. See the notch about half way down - thats the last bit of the planet leaving the sun!
