Terri,
Mercury will already be in it's transit when the Sun rises that morning. The
transit will finish by 11:00 am. If we set up around sunrise, we can show it
throughout the morning and be done by 11:00 am.
Can't show it until the Sun comes up.

I'm having difficulty with the charts
the site: http://eclipse.gsfc.nasa.gov/transit/transit.html
shows 2:57pm which -7 is 7:57am
but the chart Alex has in his above email says
11:14am and -7 would be 4:14am
We can do the 7:57 time frame, with an hour set up before hand, but
there's no way PVCC would let us set up at 3:14am for the event.
Ideas?
What do you see for the actual start time of the event?
and then an hour before for set up.
Am i reading it wrong?
Terri
This site says 11:12 universal time
https://en.wikipedia.org/wiki/Transit_of_Mercury
This site says 11:12 UT
http://eclipse.gsfc.nasa.gov/transit/catalog/MercuryCatalog.html
This site says 11:12 UT
http://www.hou.usra.edu/meetings/lpsc2015/pdf/1327.pdf
this site didn't say what time, but if it started at 11:12UT, which is -7
4:12am AZ time, then the transit is already in progress when we are setting
up at PVCC.

This site http://aa.usno.navy.mil/data/docs/Mercury2016.pdf is totally
different, it says it starts at 9:11am - 7 = 2:11am.
If no one can agree, how do we know which site is accurate?

Sam, May 9, Monday
Would you prefer BMC or Main campus?
I'm sure Loretta would be fine with a viewing up at BMC, if you want it
there.
Let me know, and i'll get it set up.

The last time we had a Mercury transit we held a PAS solar viewing at
PVCC. May 9th will be a Monday morning. I hope we can schedule a sImliar
event. We have solar scopes.
Bob Ewing and Terri, what do you think?
Kevin could do a press release like the one he did in Sept for the Lunar
eclipse. If we can"t hold it at PVCC, we could have it in a nearby park
depending on whether we open it up to the public at large. Any ideas? Sam

Thanks Kevin!
The Astronomical League had a Venus Transit certificate and pin and they
are planning to do the same with this one. We are required to take some
data, however. This will probably be the times you observed the “contact”
points, but the AL says more details are forthcoming…
They did have a list of the contact points and some other information:
---
The next planet to transit the sun is the planet Mercury on May 9, 2016.
Details on transit are available from NASA on this site: http://
http://eclipse.gsfc.nasa.gov/transit/transit.html
Note that for those of us in the eastern United States, the entire
transit will be visible. For those in the western United States, the
transit will be already in progress at sunrise, so we will not be able to
observe the entire event. Timings for the contacts are:
Event UT
Contact I 11:14, May 9, 2016
Contact II 11:17, May 9, 2015
Maximum Transit 14:58, May 9, 2015
Contact III 18:39, May 9, 2015
Contact IV 18:42, May 9, 2015
Definition of contact points:
• Contact I: when the leading edge of the planet first touches the edge
of the Sun.
• Contact II: when the planet is initially completely on the disk of the
Sun.
• Maximum Transit: when the planet is at maximum transit (the middle).
• Contact III: when the leading edge of the planet first reaches the far
edge of the Sun.
• Contact IV: when the planet is initially completely off the disk of
the Sun.
Mercury is small and so far from Earth and its silhouette is visible
only with magnification, but be sure to use proper filters to protect your
eyes.

I look forward to this event and hope to have the proper filters, etc.,
necessary to enjoy it. Maybe we’ll have a group viewing?

On May 9th, 2016, there will be a partial transit of Mercury across the
Arizona.
It will be a full transit from the East coast, but only partial here in
hours ahead of us here in Phoenix.
The transit runs from 11:12 am to 6:42pm UTC, which is, I believe, 7
provided that it's a clear day.
We should be able to view it from sunrise until 11:42 am in Phoenix,
I'll be watching. The next one is in 2019.
