Make your Solargraph

Today, the Astronomy Picture of the Day features a so-called “solargraph“. A  6 months exposure time pinhole picture:

During 6 months the tiny pinhole records the path of the Sun on the sky, revealing the seasonal changes.

Actually, this picture is part of a global initiative to create solargrpahs. From the Solar TG we encourage everyone to construct this easy device and create your own picture.

And don´t forget to send them, and us, the result!

  1. That is one of the best artistic images I’ve ever seen for astronomy. Very nice!

  2. This image should be sent to APOD.

  3. Hi George. It is APOD. I actually took it from there.

    Greetings.
