As a result of the Earth’s axis doesn’t change the way it tilts because it orbits the solar, the solar is larger in the summertime sky and decrease in winter. In the meantime dawn and sundown march north and south alongside the horizon from solstice to solstice.

You may see each results on this composite picture by Tunç Tezel (The World At Night time) exhibiting the solar’s path at summer time solstice, equinox and winter solstice in Bursa, Turkey, embedded from NASA APOD.

In my very own means I’ve saved monitor of the identical factor. Once we lived in Greenfield our home confronted west so I famous the place the solar set for each solstices and the equinox. Now we face east and I haven’t accomplished that but for dawn, however I have already got some markers.

Right here’s my japanese view at dawn yesterday morning. This is usually a marker.

I even have 4 pictures of solar pillars that are good dawn markers.

Put collectively on an japanese view picture, it seems to be like this. You may already see the solar marching alongside.

I didn’t add yesterday’s dawn to the marker picture as a result of it was too near 11 January, however the solar did certainly transfer northward in 6 days. See composite picture under.

I’m nicely on my means towards finishing the dawn markers however it can take a yr to do it. I would like each solstices and the equinox.

Attempt it for your self. Any horizon will do even for those who’re in a valley. Throughout one yr take 3 to 12 pictures, both simply the solstices & equinox or one picture monthly. Be aware the date and the solar’s location on the horizon. Put the markers in your horizon picture as I’ve accomplished above.

So the place did the solar come up in the present day?

Ummm … Not in the present day in Pittsburgh. It’s too cloudy to see the solar.
