Join us for a VERY SPECIAL EVENT...

Status updated on Monday 5/9/2016 at 2:00 PM:

SUCCESS!! We were fortunate that the dense clouds held off until after 10:30 AM
so many folks got to see the planet Mercury passing between the Earth and the Sun!

Thanks to all that came out despite the less-than-perfect conditions.
We had a great time. ;^)

This computer-generated animation of the transit of Mercury across the face of the Sun compresses 7 hours and 24 minutes into thirty-three (33) 1-second frames, each representing a 15 minute advance in clock-time and shows exactly what we'll be able to see of the Mercury transit. The Altitude and Azimuth along with the date and time (24 hour format ie 13:41:19 = 1:41:19 PM, 14:00 = 2:00PM, etc) are shown and updated from frame to frame and demonstrate the apparent rotation of the Sun due to the Earth's rotation as well as the relative motions of the Sun & Mercury through the sky. The background stars could be seen if the Sun weren't so bright! The image is un-reversed and un-inverted so you'll need to translate the view you'll see through your own inverting and/or reversing telescope - ASSUMING IT'S PROPERLY FILTERED !!!


Watch the black silhouette of Mercury glide across the Sun for its entire 7hr 24min trek.  The last time a Mercury transit was visible anywhere from Earth was on November 8, 2006. From Ohio, the next times will be November 11, 2019 followed by one on May 7, 2049. While not the rarest of all astronomical events, it's rare enough to make it worth your time & trouble to see it!
As this transit is occurring, the Sun will be 93,856,451 miles away from us observers and Mercury will be 51,818,225 miles distant. The effect this distance difference will make is that Mercury will appear nearly twice as large compared to the Sun than it actually is. Keep in mind that more than 23 million Mercurys would comfortably fit inside the Sun!

For transit information for your location, anywhere in the world, visit:

Due to the extremely eccentric (non-circular) orbit of Mercury coupled with its 7 inclination of Mercury's orbit to the ecliptic, transits occur predictably, but with an odd cadence; they occur in May or November with May transits occurring about half as frequently as November transits. Currently, they occur within a few days either side of May 8 and November 10. The interval between one November transit and the next November transit may be 7, 13, or 33 years; the interval between one May transit and the next May transit may be 13 or 33 years.

For additional information, please see this excellent article

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

Image of the June 2004 Venus transit shown below was captured by Astronomy Club of Akron member John R. Crilly

This photo shows Venus transiting the Sun - Please keep in mind that Mercury will appear to be 1/5th the diameter of Venus in this photo and 4.36% the apparent surface area - very small indeed!

Jet Stream (updates automatically to latest available image)
    The Jet Stream affects astronomical "seeing" (steadiness of the air)
    If we're in a gray area, seeing will not be as good as in a white area.
    If we're in a white area, the shorter the arrows, the better.
