After 24 hours of travel, I have arrived at the Las Campanas Observatory in the mountains north of La Serena, Chile (actually about halfway between La Serena and Copiapó on this map, just north of Santiago).
I am glad that I have a night of rest tonight, because the weather is quite bad. The temperature (at 5pm local time) is 25 degrees F (-4 C), and thick clouds are slowly drifting just overhead. Over the past few nights they've had some ice here, and a thick layer of ice is on most of the plants. We'll have to see what things are like tomorrow!
