10/25/11 – Ephemeris – The lonely star Fomalhaut
Tuesday, October 25th. The sun will rise at 8:10. It’ll be up for 10 hours and 31 minutes, setting at 6:42. The moon, 1 day before new, will rise at 8:02 tomorrow morning
There’s a bright and lonely star that appears low in the south for only seven and a half hours a night on autumn evenings. It’s appearance is a sign as sure as the falling leaves that autumn is here At 9 p.m. tonight it’s low in the south southeast. The star’s name is Fomalhaut, which means fish’s mouth. This is appropriate because it’s in the constellation of Piscis Austrinus, the southern fish. At our latitude it’s the fish that got away, because Fomalhaut appears to be quite alone. The dimness of the constellation’s other stars and location close to the horizon make the fainter stars hard to spot. They would be overhead in Australia. The earth’s thick atmosphere near the horizon reduces the stars brightness by a factor of two or more, so Fomalhaut appears to keep a lonely vigil in the south.
