The Sun crosses the celestial equator southward, so that for the next six months day will be shorter than night for north-hemisphere countries.

ILLUSTRATIONS in these posts are made with precision but have to be inserted in another format. You may be able to enlarge them on your monitor.
One way: right-click, and choose ”View image” or ”Open image in new tab”, then enlarge. Or choose ”Copy image”, then put it on your desktop, then open it. On an iPad or phone, use the finger gesture that enlarges (spreading with two fingers, or tapping and dragging with three fingers). Other methods have been suggested, such as dragging the image to the desktop and opening it in other ways.
Sometimes I make improvements or corrections to a post after publishing it. If you click on the title, rather than on ‘Read more’, I think you are sure to see the latest version. Or, if you click ‘Refresh’ or press function key 5, you’ll see the version change to the latest.
Happy Equinox!
I got a clear sight of the noon Sun today, but my measurement and timing of the Sun’s maximum height were poor. I put myself 17 nautical miles south-southeast of my true position. Anything within one nautical mile is a good sight reduction. I might try again tomorrow.
Here at 122 degrees west longitude the equinox happened at 17:05 PDT yesterday, September 22. So I tried to get a sight of the Sun at local apparent noon, 13:02. I could see the Sun through my sextant a minute or so before noon and a minute or so after noon, but the clouds were too thick at the moment when the Sun was highest in the sky. Today the weather is more clear, so I will try again. I’m happy when I can use my sights to calculate my position within a few miles of what the GPS on my phone says.
