  5. The Night Sky Friday, May 27 · With summer less than a month away, the big Summer Triangle is making its appearance in the east. Its topmost and brightest star is Vega, plain to see. Look lower left of Vega, by two or three fist-widths at arm's length, for Deneb, the brightest star in that area. Farther to the lower right of Vega is Altair, the last of the three Summer Triangle stars to rise (around 10 or 11 p.m. daylight saving time, depending on your location). Saturday, May 28 · Before sunrise tomorrow morning, look for the waning crescent Moon hanging above Jupiter. Use binoculars to check out the changing planetary array to their lower left, as shown here. · Late tonight a 7th-magnitude star in Ophiuchus should be occulted for up to 11 seconds by the faint asteroid 217 Eudora as seen from a track running from Florida through Oklahoma and Colorado to Oregon. See map, finder charts, and full information.

  6. The Night Sky Sunday, May 29 · We're still almost a month from summer, but summery Scorpius is already rearing up in the southeast these evenings. Its brightest star is fiery Antares. Look for the other, whiter stars of upper Scorpius on either side of Antares and farther to its upper right. · Libra, the next constellation west of Scorpius, reaches the meridian in the south not long after dark. Libra's lower portion contains the big dark asteroid Hygiea, magnitude 9.3, just waiting for you to hunt it out. See the article and finder chart in the May Sky & 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 4569 Baerbel along a thin track (only 9 miles wide!) running from southernmost California through Arizona, Colorado, and the Dakotas. The star 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.
