June 2009: Solstice on 21, June 2009
 

On 21, June is time to replace the exposed pinhole cans with new ones.

The name ”Solstice” is derived from the Latin sol (sun) and sistere (to stand still), because at the solstices, the Sun stands still in declination; that is, the apparent movement of the Sun's path north or south comes to a stop before reversing direction.

 

Here are solargraphs exposed in April 2009 at 67°N and 19°E. You can compare the document photograph with the solargraphs exposed face the West in a vertical and a horizontal positions.

 

 

kebne_2009_012mw                This photograph has taken in Kebnekaise, Pirttivuopio in Sweden

                in April 2009 by Pelle Lonnberg. He fastened two of my pinhole 

                cans around the stick in the middle of the picture. The exposure

                was about two weeks.
