5. The Night Sky Friday, January 25 · The Moon this evening shines not quite midway between Procyon, to its lower right, and Pollux, to the Moon's upper left. Saturday, January 26 · Full Moon (exact at 11:38 p.m. EST). The Moon is in dim Cancer, with Procyon shining off to its right or upper right during evening, and Pollux and Castor above it. · Algol in Perseus is at its minimum brightness, magnitude 3.4 instead of its usual 2.1, for a couple hours centered on 6:26 p.m. EST. Watch it gradually rebrighten though the evening. Sunday, January 27 · The Moon shines high in the east by 9 p.m. Lower left of it, by roughly a fist-width at arm's length, sparkles Regulus in Leo, as shown here. The Sickle of Leo extends upper left from Regulus. The emergence of Leo in the evening sky is always an early sign that spring is eventually coming. Monday, January 28 · Once the waning gibbous Moon is well up in the east in mid- to late evening, look upper left of it for Regulus with the Sickle of Leo extending beyond, as shown here. Look about twice as far to the Moon's right for Alphard, the fire-colored heart of Hydra. Sky & Telescope
