It’s officially fall! I just read a great blog post by John Vigor about checking your compass today – on the autumnal equinox.

Read this very interesting article by National Geographic about the autumnal equinox.

Here it is for my location today. Note that the sun’s azimuth at 19:08 (our sunset) is 270° – due West!
