Jupiter, Andromeda, and the Space Station

It was the monthly Public Night at Stephens Saturday, September 20. The late afternoon and early evening sky were not promising offering a mix of thin and thicker clouds swirled over a background of pale blue. As the Sun set, however, things improved. Jupiter came first and the first observatory visitors arrived at 7:30 -- a full half-hour before the advertised opening! The telescope revealed very good views of the planet and the Galilean moons. Aside from seeing several of the great planet's cloud bands, even some of the detail within the bands, I saw the Great Red Spot for the first time ever. Early viewing actually was best with seeing diminishing as the night went on. Also viewed were the Andromeda Galaxy (M31) looking every bit the huge fuzz-ball in the low-powered eyepiece. From there I moved the scope to the Double Cluster in Perseus: NGC 884 and NGC 869 at distances of 7,600 and 6,800 light-years respectively, and then by steps, back to Jupiter. A highlight of the night was passage of the International Space Station high overhead beginning at about 8:24. It shone brilliantly and arced steadily across the sky and low into the east where it finally fell into Earth's shadow and disappeared after a transit of several minutes. The last visitors of the evening arrived just before I was to close and they caught a glimpse of Jupiter just before it dropped behind the neighbor's trees at 10:00. In all about 50 visitors came to Stephens, 10 or 12 of them members of the College's new astronomy club. After closing I visited the Hiram site where the Aurora Astronomical Society proposed a new club observatory. The site is quite excellent protected from ambient light on all sides by trees and offering decently distant horizons. Clouds moved in and were obscuring the skies by 11:15 and overcast by midnight.
