5. The Night Sky Sky & Telescope Tuesday, May 20 As the stars come out, Saturn in the southeast, Vega in the northeast, Capella in the northwest, and Procyon in the west-southwest are all at about the same altitude (as seen from about 40° north latitude). Wednesday, May 21 The western twilight Arch of Spring is sinking, but you can still catch this big landmark when the stars come out. Jupiter in the west lies within it. Pollux and Castor, above Jupiter, are lined up roughly horizontally; they're the Arch's top. Look far to their lower left for Procyon, and farther to their lower right for Menkalinen and then bright Capella. Jupiter is moving closer to the Arch's upper-left side. Thursday, May 22 As twilight fades, spot Mercury low in the west- northwest. It's about 2½ fists to the lower right of bright Jupiter. This evening Mercury is between the horn-tips of Taurus: Beta Tauri (El Nath) to its upper right, and Zeta Tauri to its lower left. Binoculars will help. Friday, May 23 New meteor shower? A possible strong meteor shower may arrive in the early-morning hours of Saturday the 24th, timed for North America (perhaps peaking around 3 a.m. EDT, midnight PDT). For just a few hours we'll pass through the predicted debris trail of Comet 209P/LINEAR, which is making an unusually close flyby of Earth. There's even a (slim) possibility that the shower could approach "meteor storm" proportions. The comet itself is closest on May 29th, but it's very small and faint and may reach 11th magnitude at best. As dawn brightens on Saturday morning the 24th, look for Venus well to the lower left of the waning crescent Moon, as shown above.
