A Transit of Venus

Tuesday, June 5, 2012 at 6:00pm to 8:30pm

Fuertes Observatory, On the grounds

The Cornell Astronomical Society invites you to join us for a very special celestial event:

The Transit of Venus
Tuesday, June 5th, 2012 , 6 pm - Sunset
Viewed from the grounds of the Fuertes Observatory (weather permitting)

On June 5th, 2012 the planet Venus will pass directly between the Sun and Earth in a rare planetary alignment. As observed from Earth, Venus will appear as a small disc slowing passing across the Sun--an event known as a transit of Venus (TOV). There is a rich history associated with these transits; June 5th's transit will only be the 7th TOV to be observed since the early 17th century invention of the telescope. Thereafter, the next TOV will not occur until 2117!

Part of this rare display will be visible from the Fuertes Observatory on Cornell's north campus, and we invite the public to come observe with us. Solar viewing glasses and filtered telescopic views will be provided for your safe viewing pleasure.

Note: Never observe the sun without proper solar filters! Observing the sun without properly designated solar filters can result in potentially significant and permanent eye damage. You cannot safely observe the transit of Venus with the naked eye or sunglasses.

Lucky for you, CAS has all the filters you'll need.

So join CAS on the grounds outside the Fuertes observatory for this celestial alignment. The transit begins slightly after 6pm and continues until sunset (~8:30pm). Limited parking is available in the Appel parking lot across the street. We'll keep an eye on the forecast and update you on weather leading up to the event.

It was great fun to see Venus directly in front of the sun. My four-year-old son also was able to "spot" it, so it was a whole family affair. I brought my own solar-shades for safe viewing, and there was a long line for the amateur telescope that was out on the grass, so I know that was a hit. I was disappointed we couldn't go into the actual Fuertes observatory to see Venus through the telescope. We just sat on the grass with everyone else and viewed it with our solar shades, but it was a special event nonetheless.

I enjoyed it, once the skies cleared up about about two hours before sunset. I kept looking anxiously at the thick clouds hiding the sun in the mid-afternoon, but the weather gods smiled upon us in the end. I had seen the 2004 transit (that one was at sunrise at Mount Pleasant) and it was terrific to be able to see a second transit.

made me quite anxious all day, but the skies cleared up about an hour before sunset.
