It would be interesting to get some data on that. Clouds blocking the sun or
holes in the cloud cover would be a variation.
If the sun hits the enclosure, how long does it take the air inside to heat up
and then how long does it take the gear inside to warm up?
One of the classic tools for problems like this is to attach a big blob of
stuff to the crystal to dampen thermal changes. When you design your test
setup, can you leave room for a brick and collect data with and without when
you toss it into the freezer?
