Any sightings of the Venus transit?

I tried a pinhole projection but I don't see any Venus

The live video from Mauna Kea, Hawaii shows a perfect round black Venus in front of the Sun.
The live video from the Mt. Wilson Observatory shows an approximately 3ft wide bright spot without any visible details (at least not on the video feed, perhaps it is visible for the folks on site). Only for a brief period when someone held a filter between the camera and the projected sun light were Venus and sun spots visible.
I suspect my primitive pinhole camera has the similar problem. Too much light scatter to actually see the small spot where Venus blocks the sunlight.

I did the binoculars trick (see the "total eclipse" thread) and it worked great when the clouds cooperated. The orb was pretty small and hard to see, so focus was key. But a good teachable moment when you explain that Venus is (roughly) the same size as the Earth.

Didn't try snapping a picture because it's hard to hold steady.

Does it run anywhere near the San José Diridon transit station?

It did, but you missed the train

I hope you have a lot of patience if you plan on waiting for the next one. It is scheduled for December 11th but not of this year
and not next year either. In fact you have to wait until 2117!
