It’s pretty cold here – hovering around -40F (which also happens to be -40C) or so, but only 6knots of wind which puts the windchill at about -60F. On the walk out to the telescope, any exposed skin gets really really cold, to the point of hurting. I’ve been walking out with just sunglasses, a hat, and a neck gaiter, and getting cold and having to put up my hood to cut the wind. Getting tired of that, I followed the lead of some others down here and modified my ski goggles to cover my nose. Here’s a video showing them, filmed inside our science lab here at the station.
Feel free to try this at home!
