The Mercury Transit, a call for image submissions
Well, it is less than a week until the Mercury transit, and a group of individuals is looking forward to try, based on the parallax shown in images of the transit at the same time, when made from different locations from Earth, to calculate the distance between the Sun and Earth. In order for this to be successful they will need images made at the same time and know the exact coordinates of the location on Earth where the image was made. We are suggesting to not only submit your images of the transit, but if possible also an image of the full sun at exactly the full hour (if possible to the second because Mercury as well as the parallax are very small), so these enthusiasts will have data they can use. If you make an avi, please use the center time of the avi.
In addition, the ALPO’s Transit section will use the data for an extensive report to be published at a future date in the Stolling Astronomer, the Journal of the Association of Lunar and Planetary Observers (the ALPO).
We hope that Solar imagers will consider this request, and submit all their images (also partial Sun images and close ups) attached to an email with the exact time and coordinates of the location addressed to: email@example.com .
