5. The Night Sky Monday, Nov. 21 · During dawn Monday morning the waning crescent Moon points down to Saturn and Spica, as shown above. On Tuesday morning, the three form a roughly horizontal line. Tuesday, Nov. 22 · Comet Garradd continues glowing at about magnitude 6.5 as predicted, but it's getting low. Find it in the west with binoculars or a telescope right at the end of twilight. To locate the exact spot to examine, start from the head-star of Hercules (Rasalgethi) using our finder chart online or in the November Sky & Telescope, page 52. In a few weeks Comet Garradd will become too low to view well after sunset but will become more easily visible before dawn.onlineNovember Sky & Telescope Wednesday, Nov. 23 · These moonless evenings are a fine time to get out the telescope and explore the Veil Nebula and lesser-known deep-sky sights in Cygnus, which is still very high in the west in early evening. See Sue French's "Deep-Sky Wonders" article, charts, and photos in the November Sky & Telescope, page 56.November Sky & Telescope Thursday, Nov. 24 · The Great Square of Pegasus floats highest in the south these evenings. It's somewhat bigger than your fist at arm's length. Its right-hand (west) side points down roughly to Fomalhaut much, much lower in the south. Its left- hand (east) side point down roughly to dimmer Beta Ceti (Diphda), not quite as low. Friday, Nov. 25 · Tonight Jupiter's icy, enigmatic moon Europa crosses onto the face of the planet at 9:45 p.m. EST, then exits at 12:10 a.m. EST. Europa's tiny black shadow crosses Jupiter from 11:08 p.m. to 1:34 a.m. EST.icy, enigmatic moon Europa · New Moon (exact at 1:10 a.m. on this date EST). The Moon partially eclipses the Sun for Antarctica, Tasmania, and small sections of South Africa and New Zealand.
