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
The first is looking south at the Chapel. The second is facing the solar array, and the last one is in the woods near the solar array.

These two solargraphs came from an installation at Valley New School, looking East and South on College Avenue in Appleton, WI, installed around the spring equinox and taken down in May. #pinholephotography #solarcan #equinox

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

Installing a Solarcan 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 on paper #pinholephotography #solarcan
The first image is from the Oconto river, from can #38,294

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

I've been working with 5th graders in a few elementary schools to install Solarcan Pucks around the school close to the spring equinox (facing North, South, East and West). Then they learned how to process and adjust the images to show the path of the sun over the course of a few days.

A few @solarcan results from around the front yard, back yard, and down in the ravine (with a Solarcan Nebula). Front and back yard were installed in September, and the Nebula was installed in the summer. All started with trees full of leaves, eventually letting in more sun in the winter #solstice

Happy Solstice! I've harvested a few @Solarcan installations and installed a few more. More to come...

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.

Got to spend a little time with my dad taking pictures of a great horned owl family in City Park, Appleton and then a breeding pair of bald eagles across the river. There are two owlets and the mother visible. We can only see both eagles but not the eaglets yet.
