A few #Solarcan harvests from (or near) the #wintersolstice 1. 2nd Floor classroom at Appleton East, looking south. Late Aug - Dec 19. 2. SE, installed Sept 29 and removed Dec 18. This was the best exposure, showing leaves on the tree for a little while 3. South, Oct 19 - Dec 21

I found a 5 pack of @Solarcan from one of their first production runs, so I installed this Solarcan, serial #562 (normally the ones I buy are in the #30,000 or more) for a few weeks in the spring - just to see if it was still good.

3 @Solarcan were installed at the winter #solstice '24 at #lawrenceuniversity #Bjorklunden in Bailey's Harbor, WI. Collected after the summer #solstice #1 the Chapel (#31118), #2 facing the solar array (31211), #3 in the woods near the solar array (#31088).

The full @Solarcan images from these two test #Pucks

Here's a few @Solarcan Puck images from the windows at Valley New School in Appleton. They have some amazing views of downtown Appleton!

Here's a couple @Solarcan installations (#38326 and #39813) I had installed in Appleton, WI near the winter solstice and collected near the summer solstice #solstice #solarcan

Here are a few Solarcan images I haven't shared yet. The first batch were taken from the roof of elementary schools (Berry, McKinley and Richmond) in Appleton - installed in early January, and taken down in May to share with students. #Solarcan #pinholephotography #solstice

The last image was overlooking the Mississippi river in Onalaska, from can #39,838. This Solarcan installation was slightly disturbed from a recent storm, and you can see the diverted angle of the sun's rays that show that the can was moved.

This image is from Appleton, can #39,806. The scan looked a little over exposed, so I processed it in black and white. The last image was overlooking the Mississippi river in Onalaska, from can #39,838.

Installing a @TheSolarCan pinhole camera between the winter solstice and spring equinox is a unique time in the N hemisphere, with no leaves on trees and the sun isn't too high, so it gets fully captured #pinholephotography #solarcan This image is from Oconto, WI #38,294

Northern Lights pics from Thursday taken with a Pentax K-1, 10 second shutter, f-2.4 and various ISOs. We were just north of Appleton, so you can see a plane taking off from Green Bay.

From listening to the episode today, I reserved and checked out all three books @DouglasMGordon talked about today on Beta wpr.org/shows/beta/bet…

(4/5) I got better results from the turbine. Of course, the turbine was running, so I didn't capture the blades. To get these images, the #Solarcanpuck was really low and angled up. One of the Pucks was actually taped to a rock on the ground.

Early in the week, I placed a @Solarcan facing the chapel at Lawrence University's Björklunden, and removed it on the #Solstice. Again, the clouds and rain prevented some of the sun's path to really develop. Maybe a longer exposure in the fall?

(5/5) Here are a few nice images, but they didn't capture any sun.
