5. The Night Sky Friday, November 22  The waning gibbous Moon is up in the east by about 10 p.m. tonight (depending on where you live). Look above it for bright Jupiter and, to Jupiter's left, Pollux and Castor. To the Moon's right twinkles Procyon. Much farther to the right, brighter Sirius is rising or soon to rise. Saturday, November 23  The eclipsing binary star Algol should be at minimum light, magnitude 3.4 instead of its usual 2.3, for a couple hours centered on 9:06 p.m. Eastern Standard Time. It takes several more hours to fade and to rebrighten. Sunday, November 24  During dawn Monday and Tuesday mornings, when you're preparing to use binoculars or a telescope to make one last pre- perihelion try for Comet ISON barely above the horizon, you'll find Mercury and fainter Saturn shining to the naked eye just 3/4° apart (at the times of dawn in North America). They're well above the spot to look for the comet: by 7° on Monday, 9° on Tuesday. In a telescope, Mercury will be a tiny, slightly gibbous disk 5.6 arcseconds in diameter (no bigger than Mars, high in the southeast), while Saturn is dimmer but much larger: 34″ across its rings. They're a nice consolation prize! Monday, November 25  Last-quarter Moon (exact at 2:28 p.m. EST). The Moon rises around 1 a.m. tonight. By dawn Tuesday morning it's high in the south, with Regulus to its right and Mars to its lower left. Sky & Telescope
