March 30. Finally saw Mercury, from the parking lot of the fire station in Beacon, where we had a good view west across the Hudson. After a few minutes, a white-haired man came out of the building and got into his car. Everything all right? They’d be having an event on Palm Sunday. – Mercury together with Jupiter, Venus, Mars. I was very surprised that Mercury was so much brighter than Jupiter, though it was clearly indicated in the app. Reading star charts like music scores. Also lots of airplanes moving through the evening sky like big, slow spaceships.
