5. The Night Sky Sky & Telescope Tuesday, February 24 Soon after nightfall, look upper right of the Moon for the Pleiades and upper left of the Moon for Aldebaran and the Hyades. One of the most famous challenge objects for amateur astronomers is Sirius B, Sirius's white-dwarf companion. The pair has been widening for the last two decades, and now Sirius B stands a good 10.7 arcseconds to Sirius's east. A much easier white dwarf is Omicron 2 Eridani B, also described there and also now in the evening sky. Wednesday, February 25 Look for Aldebaran shining near the first-quarter Moon. Thursday, February 26 Watch Jupiter's satellite Europa reappear from eclipse out of Jupiter's shadow at 10:23 p.m. EST (7:23 p.m. PST), just off Jupiter's eastern limb. Mercury is at greatest elongation low in tomorrow's dawn, 27° west along the ecliptic from the Sun. Friday, February 27 Venus and Mars in the western twilight have widened to be 2.7° apart. Find faint little Mars beneath Venus. Saturday, February 28 Early this evening, the dark limb of the waxing gibbous Moon will occult (cover) the 3.6-magnitude star Lambda Geminorum for North America east of the Mississippi and north of the deepest South.
