What has happened to winter? January ends with warm and cloudy nights. Unseasonably warm! This next week will bring more clouds and a chance of rain! We may have a couple of clear nights to observe. Follow the moon, as it brightens the night sky and discover several familiar Constellations this week.
Sunday night, The Moon shines about 8° right or upper right of Jupiter this evening (for North America.
Monday, The first-quarter Moon shines about 8° upper left of Jupiter this evening (for North America).
Tuesday, Jupiter is lower right of the Moon this evening. Continue the line much farther lower right to hit Venus. OK Rock hounds, On Tuesday, January 31, asteroid 433 Eros will come closer to Earth than it has in 37 years, traveling across the night sky in the constellations Leo, Sextans and Hydra. At its closest pass of 16.6 million miles (26.7 million km) the relatively bright 21-mile (34-km) -wide asteroid will be visible with even modest backyard telescopes, approaching magnitude 8, possibly even 7.
Wednesday, The Moon shines between the Pleiades and Aldebaran
Thursday, Now that it's February, Orion strides high in early evening. It's below the Moon tonight. Orion's top left corner is fiery Betelgeuse. Far below Betelgeuse shines brighter Sirius. Betelgeuse and Sirius form the equilateral Winter Triangle with Procyon off to their left.
Friday, After dinnertime, the waxing gibbous Moon is shining high in the southeast. Look to its upper left for bright Capella, to its upper right for Aldebaran, lower right for Orion, and lower left for Gemini including Castor and Pollux.
Saturday, The Moon shines in the feet of Gemini this evening, with Castor and Pollux to its left and Orion farther to its right. Well below the Moon shines Procyon
