This Week's Sky at a Glance
Some daily events in the changing sky for May 27 – June 4.

Friday, May 27
With summer less than a monthaway, the big Summer Triangle is making its appearance in the east. Itstopmost and brightest star is Vega, plain to see. Look lower left ofVega, by two or three fist-widths at arm's length, for Deneb, thebrightest star in that area. Farther to the lower right of Vega isAltair, the last of the three Summer Triangle stars to rise (around 10or 11 p.m. daylight saving time, depending on your location).
Watchthe Moon pass over the dawn planet lineup in the closing days of May.(The visibility of the fainter objects in bright twilight is exaggeratedhere. These scenes are always drawn for the middle of North America.European observers: move each Moon symbol a quarter of the way towardthe one for the previous date.)

Before sunrise tomorrowmorning, look for the waning crescent Moon hanging above Jupiter. Usebinoculars to check out the changing planetary array to their lowerleft, as shown here.
Late tonight a 7th-magnitude starin Ophiuchus should be occulted for up to 11 seconds by the faintasteroid 217 Eudora as seen from a track running from Florida throughOklahoma and Colorado to Oregon. Seemap, finder charts, and full information.

We're still almost a monthfrom summer, but summery Scorpius is already rearing up in the southeastthese evenings. Its brightest star is fiery Antares. Look for theother, whiter stars of upper Scorpius on either side of Antares andfarther to its upper right.
Libra, the nextconstellation west of Scorpius, reaches the meridian in the south notlong after dark. Libra's lower portion contains the big dark asteroidHygiea, magnitude 9.3, just waiting for you to hunt it out. See thearticle and finder chart in the MaySky & Telescope, page 56.
Early Monday morning an unusually bright star, 4.9-magnitude Nu Pegasi,will be occulted for up to 1.2 seconds by the small asteroid 4569Baerbel along a thin track (only 9 miles wide!) running fromsouthernmost California through Arizona, Colorado, and the Dakotas. Thestar will be low in the southeast.Maps and details.
Monday, May 30
Saturn's biggest and brightest satellite, Titan, is about four ring-lengths east of the planet tonight.
Tuesday, May 31
The brightest star in theeast these nights is Vega. You can't miss it. Look for the littletriangle-and-parallelogram pattern of the constellation Lyra dangling toits lower right.
The galaxies of the great VirgoCluster are numerous but not that bright as Messier objects go.Nevertheless, if you have a dark sky, even binoculars are enough for youto hunt for ten of them as very faint smudges west of Epsilon Virginis.Use Gary Seronik's Binocular Highlight column and finder chart in theMaySky & Telescope, page 45.
Thefour-planet lineup before sunrise continues to lengthen, with Jupitermoving farther to the upper right and Mercury to the lower left. The 10°scale is about the width of your fist at arm's length.

Meanwhile, the dawn planet lineup continues to lengthen in the east, with Jupiter now very plain and easy.

Saturn (with Porrima nextto it) and Spica draw the eye in the south after dusk. But don't forgetCorvus, the Crow, below them. Corvus's uppermost bright star, DeltaCorvi, is a wide telescopic double: magnitudes 3.0 and 9.2, separation25 arcseconds.
New Moon (exact at 5:03 p.m. EDT). Apartial eclipse of the Sun will be visible from much of the arctic.Parts of Japan, Alaska, and the Canadian Maritimes will also experience avery slight partial eclipse.Maps and details.
Thursday, June 2
Saturn and Porrima havenow closed to 17 arcminutes of each other, practically as close as theywill get. Although they look like neighbors, Saturn is only 76light-minutes from Earth, while Porrima is 39 light-years in thebackground. That's more than a quarter million times farther away!
The waxing Moon adorns the western twilight.

Look west in twilight for thin waxing crescent Moon far below Pollux and Castor, as shown here.
Are you light-polluted where you live? Most of us are. But don't be discouraged by the astronomy you can't do, concentrate on what you can. For instance, see Hugh Bartlett's "Binocular Sights for City Nights," with finder photos, in the JuneSky & Telescope, page 52.
Saturday, June 4
In twilight, look forPollux and Castor to the upper right of the Moon, and look for Procyondisappearing about equally far to the Moon's lower left, as shown here.
