5. The Night Sky Tuesday, February 17 Mars is now just 2° above Venus in the west-southwest at dusk. They'll remain at least this close for the next nine days. The shadow of Jupiter's moon Io crosses Jupiter's face from 6:13 to 8:31 p.m. EST. It's following along sixteen minutes behind Io itself, which is less visible. Around 9:10 p.m. EST, Callisto disappears into occultation behind Jupiter's western limb. Then from 10:35 p.m. to 1:30 a.m. EST Europa's shadow crosses Jupiter, following thirty-five minutes behind Europa itself. And, Jupiter's Great Red Spot comes into view around the planet's celestial eastern edge by midnight EST, to reach the planet's central meridian around 1:47 a.m. EST. Wednesday, February 18 Juno, the 3rd-discovered asteroid, was at opposition three weeks ago but is now better placed for evening viewing. It's a little west of the head of Hydra (which is west of Jupiter) and magnitude 8.5. With your telescope, work your way to its exact position using the chart in the February Sky & Telescope, page 50. Thursday, February 19 Algol is at its minimum light for a couple hours centered on 9:17 p.m. EST. Mutual eclipse among Jupiter's moons. Io casts its shadow onto Ganymede from 7:35 to 7:43 p.m. EST this evening, dimming it by 0.8 magnitude — that is, reducing its brightness by half — at the middle of that time. Friday, February 20 Venus, the thin crescent Moon, and little Mars form a tight bunch in the west-southwest during and after dusk, as shown above. They fit in a circle just 2° across at the times of dusk for most of North America. Sky & Telescope Saturday, February 21 Venus and Mars are in conjunction 0.4° apart at dusk, with the Moon now looking on from on high, as shown above.
