A changeable sky

Even before heading to Stephens Memorial Observatory conditions were changeable. The mixed forecasts called for partly cloudy skies with the chance of isolated thunderstorms. Seeing conditions, well, the forecast was from no good to okay. As it turned out, all of those things were true! I opened the Observatory and my first visitors for the night began arriving shortly thereafter. Due to neighboring trees, we hauled the portable 10-inch reflector out to the lawn to catch a look at the Moon which was floating in clear sky. Nice views enjoyed by all present. Even as we watched a shelf of clouds moved steadily from the northwest first obscuring, then covering the Moon. As a few more folks arrived we talked about telescopes and adjourned to the Observatory interior to see and discuss the big refractor. In all 23 people took a chance that the sky would be clear enough and visited. By about 10 PM we were all talked out, there were flashes of lightning in the sky along with rumbles of thunder. I closed up, picked up my gear and loaded the car. As I left I could see patches of clear sky and one of my intended showpieces --Antares, the red supergiant star in Scorpius-- shining through a "sucker hole" in the southern sky. In the west, flashes of lightning. It was a changeable sky indeed!
