Today's post is a little different from normal: no sewing, no minis. Why? For the last time in my lifetime Venus was transiting the sun.
Just like when you view a solar eclipse, you should not look directly at the sun. Many schoolchildren the world over have created pinhole viewers from boxes or paper bags with which to view such events. I used an old mailing tube that usually holds my drafting assignments from highschool.

It was cloudy most of the afternoon while I waited for the 6pm-ish start of the transit so I only got to test them out a little beforehand.
So just what is the transit of Venus, anyway?
Venus is closer to our sun than we are, so occasionally it comes in between us. This is just an ordinary day for Venus, but it's a fun astronomical treat for us here on Earth.
And it won't happen again until 2117, so unless within my lifetime life
span is markedly increased, almost no one alive now (and old enough to
appreciate it) will be alive to see it then. It seemed worthy of a little party to me.

It wasn't long till the transit was about to begin, so my husband and I headed outside to try out the viewing tubes. I had a couple pieces of white cardstock to hold at the viewing end of the tube for us to view the image on.

The large tube did, indeed, give a larger image but was soooo much harder to site/ aim. Also, as you might expect, the image wasn't as clear.

Nevertheless we could see the transit happening (in between cloud passes) even if it was practically impossible to capture on the camera what we were seeing with our eyes.
After texting back and forth with my family I remembered that we could also use binoculars to view it. The image would be smaller but much clearer.

Hard to photograph, the camera is at a fairly steep angle to the paper which is why it looks like an ellipse and not a circle, but we could clearly make out Venus as well as a couple of sun spots.
My mother had much better results with her small telescope. In fact it makes me wish a little bit that I would have dragged the whole family and anyone I could think of up to her place to see it like that.

We were able to watch a live video feed (which was especially nice after the sun ducked behind clouds, trees, and houses here) of the transit from the observatory at Mauna Kea, Hawaii.
They had several different filters they were switching between, each giving a slightly different view of what was going on on the sun.

And they also had some beautiful (sort of) live shots streamed in from the SDO.

Happy Friday, all!
