Haldun Menali 2012 Transit of Venus



(click image to view & discuss)

The first notch by Venus

My wife Gamze and I traveled to Southern California to watch the last transit of Venus of the 21st century. We viewed the transit with the members of the Local Group Astronomy Club (http://www.lgscv.org/) in Santa Clarita, CA. The skies were perfectly clear, the location was at the very end of a shopping mall parking lot (http://www.meetup.com/LAAstronomy/events/66566582/), we watched the transit for about 5 hours, from the start until the sunset, and our short trip was a complete success.

Site coordinates:  N 34o 24' 57"   /  W 118o 30' 31"
Centre Pointe Development in the Canyon Country area of Santa Clarita, CA
Transit start at 3:06 pm PDT
Sunset at 7:52 pm PDT

The 'black drop' effect

This is one of many frames on which I was able to capture the so-called "black-drop" effect.

Venus 'moves in'

The planet Venus starts its 6+ hour journey over the Sun's disk.

About mid-transit

A couple of large sunspots kept company to the transiting Venus throughout the event.

Jupiter and its moons? No, thin clouds during the transit

As the Sun sunk down toward the western horizon, a few high cirrus clouds got in its way, creating this illusion.

Getting down to western horizon...

More thin clouds moving in front of the setting Sun, and reddening effect due to light traveling through a ticker layer of atmosphere as the Sun goes down.

The 'flattened' Sun & Venus

Again, due to the atmospheric effect, the setting Sun seems to be an ellipse rather than a circle.

The disappearing act - part 1

What you are seeing is the setting Sun, with the planet Venus in transit, behind a mountain peak. I believe these are the peaks of the Hopper Mountain National Wildlife Refuge due west from our viewing location.

After the sunset - farewell for 105 years!

..... unless there would be a medical miracle by then, no one alive today will be able to see the transit in 2117!

Venus Transit at H-alpha

One of the few afocal pictures Gamze took with her Kodak M1033 point-and-shoot camera through our Lunt 60mm H-alpha solar scope. Nice shot showing the transiting Venus and solar prominences.

Transit through a Smartphone

This is my first and only try of taking a shot of the transit with my Blackberry through the Lunt 60mm H-alpha scope.
