இனிய அதிகாலையின் அன்பு வணக்கம். இன்று காலையில் கோள்களின் நிலை. Mars (magnitude 1.5) rises around 2 or 3 a.m. near Regulus (magnitude 1.4) in Leo. By dawn theyre high in the east. Mars and Regulus are moving farther apart now, from a separation of 2.5° on October 19th to 6.5° on the 26th. In a telescope Mars is just a tiny blob 4.7 arcseconds wide. Comet ISON is also near Mars, but its still a faint telescopic target at about 10th magnitude. Use the finder chart for it in the November Sky & Telescope, page 50. Jupiter (magnitude –2.2, in Gemini) rises in the east-northeast around 11 p.m. and blazes high in the south by early dawn. About 8° left of it after it rises are Castor and Pollux. Friday, October 18 Full Moon. A slight penumbral eclipse of the Moon will be detectable this evening by careful Moon-watchers in the eastern half of North America. The Moon will pass deepest through the pale outer fringe (penumbra) of Earths shadow around 7:50 p.m. Eastern Daylight Time (EDT). Look for unusual shading on the Moons south-southeastern side. Weaker shading should be detectable for at least 45 minutes before and after. In Europe and Africa, the penumbral eclipse happens in the middle of the night when the Moon is high: centered on 23:50 Universal Time
