Someone has suggested using a welding helmet to look diectly at the sun.
As I said in another topic, I used to do orientation up to the accuracy of 0.1 degrees with the help of the sun while in the army. We had theodolites that had attachable solar filters, especially made for this purpose.
It's worth noting that while anyone can buy theodolites for civilian use as well, they don't necessarily have solar filters as default: the method used is needlessly complicated for civilian use, because in civilian use there usually are some fixed points available for accurate orientation (unlike in enemy territory), and apart from that there's just no reason to use the theodolite to look at the sun. So if someone wants to try this, make sure you use a solar filter purposefully intended for this use.
This silly debate just isn't worth blindness.
I am a relative newcomer to the FES websites. I have only been here about 3 years. But it has just gotten worse and worse over that time. Most of what you get from FE's now are.:
(1) Ignored
(2) "It's fake !"
(3) Insults
(4) Profanity
(5) Vulgarity
(6) And probably a lot of the other
I could give you some examples, but you've probably seen them all.
One had to with the distance from the earth to the moon and how the measurements were done.
But it is becoming an interesting website for the interesting facts posted by the so-called "globulists" , "roundies", "round earthers", et cetera, et cetera, and so forth !
In a way it has become educational and entertaining.
As I said previously this old "sinking ship" is an example of your "This silly debate just isn't worth blindness." to us ancient mariners and navy veterans.LOL.
