5. The Night Sky Friday, May 31 · Mercury, Venus, and Jupiter have stretched out into a nice straight line 7° long, as shown at right below. Look low in the northwest after sunset. The line will continue to lengthen day by day, as Jupiter descends to the horizon and Mercury pulls a bit higher above Venus. · Last-quarter Moon (exact at 2:58 p.m. EDT). The Moon rises around the middle of the night. Saturday, June 1 · Vega, the brightest star in the east these evenings, is currently the top star of the huge Summer Triangle. Look to Vega's lower left, by two or three fists at arm's length, for Deneb. The third star of the Summer Triangle is Altair, considerably farther to Vega's lower right. Altair is just rising in the east as dusk fades away. How early in the evening can you spot it? Sunday, June 2 · The best time to view Venus in a telescope is in late afternoon well before sunset, when it's still at a high altitude in relatively steady air. Mercury and Jupiter are in the same vicinity, but they're tougher catches in broad daylight. Pick them up them using the day-by-day finder chart for all three above the afternoon Sun in the June Sky & Telescope, page 51.June Sky & Telescope Monday, June 3 · "Cassiopeia" usually means "Cold!". Late fall and winter are when this landmark constellation is high overhead (seen from mid-northern latitudes), but even on hot June evenings it's lurking low. After dark, look for it down near the north horizon. It's a wide, upright W. The farther north you are the higher it'll appear. But even as far south as San Diego and Atlanta it's completely above the horizon. Sky & Telescope
