Lahaina Noon +2

A reader suggested a followup to my Lahaina noon photos, and since I’m always game for a backyard science observation, here are similar pictures taken at the solar noon (12:35pm) today, two days after the Lahaina noon. You can see the shadows are no longer straight down, and from all my reading on the subject, I know they are pointing due south at that moment. Incidentally, this proves the earth is round…

Oddly, the fence has less of a shadow because it has a top bar above the post and offset from the chain link. So at Lahaina noon, the bar casts a shadow next to the chainlink fence, but today they overlap.

The sun has moved a few minutes of a degree further north, and the pole of our clothesline is now a sundial.

Be sure to mouse-over the photos on my blog because I often put some explanations in the pop-up text.

I just noticed that the EXIF dates on all my Lahaina noon photos are false because I’ve been using an old camera whose internal clock batteries are worn out.

    Aloha Andy, (I hope that’s right). Thanks for the followup….the effect wasn’t as noticeable as I would have expected…but that’s what was informative about the experiment. Thanks for taking the time and courtesy to respond to a reader’s request.

    Keep Writing!…we enjoy your blog very much.

    Mahalo,

    Thanks for reading Mike, with that kind of encouragement, I’ll try to write more.

    The sun at noon will be furthest north on the summer solstice, June 21st. So if I remember about it, I’ll take a photo for comparison.
