Venus transit SUCCESS!

We had to endure rain, thick clouds that teased us by appearing to clear then thicken again. The clock kept ticking away precious time since we only had until 8:32pm when the Sun would set behind the trees. And then, suddenly, at 8:04pm, with 28 minutes remaining, the clouds cleared and we were rewarded with views of the Sun with Venus in transit. We estimate that 200 people stayed through the awful conditions and were rewarded with a view of the actual event in progress and remained in view until it disappeared behind the trees at 8:32pm, right on schedule. It truly was a "bottom of the 9th, two outs, full-count grand-slam" victory.
There were lots of smiles. ;^)

Join us for a VERY SPECIAL EVENT...

No one on Earth will see this happen again for over 105 years

This computer-generated animation of the transit of Venus across the face of the Sun compresses 2 hours and 50 minutes into seventeen 1-second frames, each representing a 10 minute advance in clock-time showing exactly what we'll be able to see of the Venus Transit. The Altitude and Azimuth along with the date and time (24 hour format ie 18:00 = 6:00PM, 19:00 = 7:00PM, etc) are shown and updated from frame to frame since the whole event is steadily sinking into the west due to the Earth's rotation. The image is un-reversed and un-inverted so you'll need to translate the view you'll see through your inverting and/or reversing telescope.
Watch the black silhouette of Venus glide across the sun for 2 hours of its total 6.8 hour trek.  The last time a Venus transit was visible anywhere from Earth was on June 8, 2004 and the next time will be December 11, 2117 - 105
years from now!
While this transit is occurring, the Sun will be 94.3 million miles away and Venus will be 26.8 million miles away from us so Venus will appear 3.5 times larger compared to the Sun than it actually is.

WARNING!!  To observe this event, specially equipped telescopes are absolutely required!

Where you can go to safely view this rarest
of all predictable astronomical events...

ACA members and others will be set up with proper
viewing equipment at locations throughout northeast
Ohio to bring this event to as many people as possible
Viewing locations will be posted here as they become known:

Due to the 8:13 ratio of the orbits of Earth and Venus (the Earth makes 8 orbits around the Sun in almost exactly the same time as Venus completes 13 orbits), coupled with the 3.39 inclination of Venus' orbit to the ecliptic, transits occur predictably, but with an odd cadence; always in pairs whose elements are separated by almost exactly 8 years and time between  pairs alternating between 105 years and 121 years.

As you can see, Venus transits don't happen often.
Let's hope for clear skies since we won't get another chance!
