The Sky This Week for February 10 thru February 12

Wolf HowlingThe Sky This Week for February 10 thru February 12

Friday, February 10

Full Moon arrives officially at 7:33 p.m. EST, but it looks completely illuminated all night. You can find it rising in the east at sunset and peaking in the south shortly after midnight local time. It dips low in the west by the time morning twilight begins. The Moon spends the night in western Leo, not far from the Lion’s brightest star, 1st-magnitude Regulus. Look carefully this evening and you should notice the distinct dusky shading of a penumbral lunar eclipse over Luna’s northern half. The eclipse peaks at 7:44 p.m. EST, when 99 percent of the Moon lies within our planet’s light outer shadow.

Although asteroid 4 Vesta reached opposition and peak visibility in mid-January, the brightest minor planet of 2017 still shines at magnitude 6.8 and shows up quite easily through binoculars. To find the minor planet, start at magnitude 1.2 Pollux in northern Gemini and then drop 2.4° southwest to magnitude 4.1 Upsilon (u) Geminorum. Vesta lies 0.5° south-southeast of Upsilon this evening.

Sunday, February 12

Mars continues to put on a nice show these February evenings. It appears nearly 30° high in the west-southwest once twilight fades to darkness, though it’s easier to find by looking 6° (about one binocular field) to the upper left of brilliant Venus. The magnitude 1.2 Red Planet currently lies among the background stars of Pisces the Fish. A telescope shows the world’s 5″-diameter disk, but you likely won’t see any surface detail.
