Make that “same-time images.” The two sets of photos must be taken at the same
time.

One thing, if I’m reading the requirements correctly, is that anyone can pair
up with anyone else. That is, if Ted and Bob get images at exactly 9am, 10am
and 11am Phoenix time (1800, 1700 and 1600Z), anyone else in the club can use
their images same-time to perform the measurements and calculations. Bob and
Ted can only pair up with one of us, but I see no prohibition against anyone
or everyone using these images to compare with their own.
Bob and I have a PowerPoint slide set that describes the details. I plan to
use them at the May 5th meeting to show what this is all about. I will be
happy to send a PDF to anyone who may not be able to attend the May meeting.

P.S. There are options in case the sky is cloudy at one or both locations,
allowing an AL member to use imaging over the Internet at one or even two web
locations to gather the data. I asked if a screen shot of a live stream was
okay. I also pointed out that the only “remote imaging” site I could find, at
iTelescope.net <http://itelescope.net/>, told me they do not offer a solar
imaging service at this time. The AL coordinator said he would contact some
others and let me know how they plan to change these options.
P.P.S. The AL’s Transit of Venus (in 2012) did NOT require two sets of
images. You only had to make a sketch and then go to a NASA site to do three
“activities,” one of which was to download their images and plug in your
measurements to get the calculated value of 1 AU.

I will be on the East coast for the Mercury transit and would love to try
this with club members back here in Phoenix. It's about time we knew how
far away the sun was! 🌝

Alex,
the May 5 meeting would work good for a discussion about this project, if
you want to prep something about it. Dan doesn't usually do too long of a
presenation, so we should have time after his talk to discuss the Mercury
transit
Sam, is this ok with you and should we put it on the agenda?
I want to hear about it, even if I'm not planning to do it. Sounds
intriguing.

The Astronomical League is offering an award (pin and certificate) for
meeting the requirements as stated on their website http://astroleague.org ;
<http://astroleague.org/>. Scroll down to “Mercury Transit Special Award is
now here” and click on the word “here” at the end of that paragraph. This
page has all the requirements you must meet in order to receive the award.
All members of PAS are automatically PAS club affiliates of the AL so your
first requirement is already met.
The next set of requirements are not for the faint at heart. They involve
the cooperation of two observers at some distance apart (PVCC to BMC should
be enough) and a lot of trigonometry. You and your partner will be using
the separate observations to calculate “1 AU” the distance from the Earth
to the Sun.
I need to look at the details more carefully first, but I’d like to propose
a short talk about this at an upcoming meeting if there is any interest.
Alex
