Black Drop Effect526 viewsFirst Contact plus 11 minutes. Venus appears to be glued to the rim of the Sun's disk. This is known as the "Black Drop Effect."

First Contact525 viewsVenus takes a tiny nibble out of the Sun's disk just past the 5 o'clock position.

The Sun - Just prior to First Contact (Hydrogen-Alpha View)486 viewsVenus has not yet begun to encroach on the Sun's disk

OCA Club Observatory483 viewsThe Club Observatory (right) houses the 22-inch Kuhn telescope.

A Serious Setup on the Upper Pads471 viewsA very nice TEC refractor on an Astro-Physics mount; both the main and guide scopes have white-light solar filters.

My Setup on the Upper Pads461 viewsI set up where I could get a good view of the Sun all the way from first contact to sunset.

Sunset, 7:57 PM458 viewsThe unfiltered setting Sun.

First Contact plus 28 minutes456 viewsVenus is well on its way across the Sun's disk.

First contact plus 4-1/2 hours - White Light View454 viewsFor the last act I switched to a mylar white-light filter, just for a change of pace.

The Upper Pad area453 viewsI wound up camping out on the Upper Pad area at the OCA Anza site, where I had plenty of company.

Second Contact444 viewsFirst contact plus 16 minutes - Venus has now "detached" itself from the Sun's rim and is heading inward.

First Contact plus 1 minute 28 seconds439 viewsThe nibble on the sun is a little larger.
