A group of science students came all the way from Spain to watch the eclipse in Mackay Idaho. They brought a collection of telescopes, sun filters, and weather balloons. They released a balloon just before the eclipse, presumably to measure the eclipse induced temperature drop which was considerable. Mackay’s elevation is almost 1800 meters. When the Sun goes down the temperature drops. The wind was blowing from the north and their balloon took off towards the south. They probably had a little road trip to recover it.
