The temperature drop was something I wasn't prepared for when I saw the 2017 eclipse,
During a partial eclipse in Southern California circa 1991, the only things noticeable were that the sunlight seemed only slightly dimmer (something what would have gone right past us if we weren't expecting it), but we definitely felt the drop in temperature.
The company I was working at the time made computer-controlled greenhouse control systems, part of which is a weather station. The computer also compiled sensor data from the weather station and the zones in the greenhouse. We immediately printed out the weather station data for the eclipse and were surprised at the very definite drops in the readings, especially the size of the drop in light. I saved that printout for posterity, but have long since lost track of it.
