The Sky This Week for June 16 to June 19

A virtual who’s-who of our planetary neighbors will be out in the sky this week for you to find.

Thursday, June 16

• The conspicuous Summer Triangle asterism dominates the eastern sky in late evening. Vega, the triangle’s brightest member, shines at magnitude 0.0 and stands highest of the three stars. To its lower left lies Deneb; at magnitude 1.3, it’s the faintest of the trio. Magnitude 0.8 Altair completes the bright asterism. Despite its name, the Summer Triangle appears prominent from late spring until the onset of winter.

Friday, June 17

• The waxing gibbous Moon forms the apex of a flat isosceles triangle with Mars and Saturn tonight. The Moon stands highest and about 10° from both planets; Mars and Saturn lie approximately 18° apart.

Saturday, June 18

• The Moon passes 3° due north of Saturn at 8 p.m. EDT. For observers in North America, the two appear between 3° and 5° apart throughout the night.

Sunday, June 19

• Full Moon officially arrives at 7:02 a.m. EDT tomorrow morning, but it looks completely illuminated throughout the night. It appears low in the southeast as the Sun sets and reaches its peak in the south around 1 a.m. local daylight time. For North American observers, the Full Moon crosses from Ophiuchus the Serpent-bearer into Sagittarius the Archer during the evening hours.
