I'm not sure that's a good idea, but it does remind me... One thing I remember about a solar eclipse I saw was once it began, and a tiny corner of the sun was covered, all the heat from the sunshine seemed gone. We were in the middle of a hot field under some trailer awnings. It was miserable in the sun until just 1% of the sun was covered, and then the sunshine was barely different than the shade. There was no visual difference in the sun, but you could feel the change in radiant heat.

> until just 1% of the sun was covered Was this confirmed? It's easy to underestimate because the sun is so incredibly bright that it bleeds outside and maintains it's perceived intensity and radius much more so than the actual numbers, due to various optical phenomena. For instance, our eyes have logarithmic intensity response curve, so a 2x increase feels more like – say – a 1.1x increase.

  No, it's a subjective estimate. Everything I said is subjective. I did look at the sun with glasses that made it appear as a dim orange ball, and as soon as the moon barely started to cover an edge it was comfortable to walk around in the sunshine. By totality we were all wearing jackets. This was in Idaho.
