I am partnering with Billy Zigouras on Test the Curve Day 2020.

I will be organizing several different tests.  You can participate here or find a place to partner on the Facebook page.

Tests to be performed:

• Sun’s angle at local solar noon on the day of the Match Equinox.
• Left to right curve with an external straight edge as a reference.
• Reciprocal zenith angles.
• Test if the horizon rises to eye level?
• Long-distance observations to test if we see too far.

 

There will be a dedicated page for each measurement with instructions on how you can participate.  If you have other ideas, email mctoon@mctoon.net.
