Endurance of an observer of the Sun.
My mobile solar observation usually starts by parking my car, then setting up the telescopes, etc, following by anything from 60 - 120 minutes of observation.
After that, the equipment are packed, and I'll climb into the driver's seat.
When I started the engine yesterday, the thermometer reads 37C (outside temperature). And for today, it is 40C!
