This report marks the completion of already two thirds of the Daily Oak project. Hard to believe!
I knew in advance that I would miss quite a few days this month because we went on our family summer vacation, and after our return I took yet another four-day trip with my son, all of which kept me out of town for a total of 21 days. I did not find many interesting or impressive trees during those days – so I have only 11 guest trees.
Looking over my collection for this month I realize that I happened to be at the tree between 9 a.m. and 11 a.m. four times. This gives one a good impression of how quickly the shadow moves, looking from perspective a. Here are three of the four pictures (there wasn’t really a shadow on the fourth because of an overcast sky):
|August 28, 10:21 a.m.|
|August 23, 10:41 a.m.|
|August 19, 11:00 a.m.|
Perspective b, on the other hand, shows clearly how the late afternoon sun passes beyond the tree top within three hours.
|August 18, 4:36 p.m.|
|August 29, 5:05 p.m.|
Once I got to the tree just as a small airplane was approaching the nearby local airport:
|August 21, 5:00 p.m.|
