The Night Sky
Monday, July 18
· Arcturus is the bright star shining high in the
southwest these evenings, far above Saturn and Spica.
Arcturus is a yellow-orange giant 37 light-years away and
about 150 times as luminous as the Sun. Its pale gingerale color is plain to the unaided eye. Compare this to the
icy blue-white of Vega overhead, equally bright.
Look far to the right of Arcturus, at roughly the same
height, for the Big Dipper, oriented about as shown here.
Tuesday, July 19
· Mercury is at greatest elongation this evening, 27°
east of the Sun, low in the west-northwestern twilight.
Wednesday, July 20
· Now's the time of year to work through the rich but low
tail of Scorpius with a telescope right after dark. Explore
a whole nest of little-known star clusters near M6, the
Butterfly Cluster, with Sue French's Deep-Sky Wonders
article and chart in the July Sky & Telescope, page 66.
The Big Dipper high in the northwest is starting to dip.
Thursday, July 21
· The brightest asteroid, 4 Vesta, has brightened to magnitude 6.0 as it approaches opposition in Capricornus.
It's easily visible in binoculars in late evening; use our online finder chart or look in the August 2011 issue of Sky
& Telescope, page 53. The Dawn spacecraft has taken up orbit around Vesta and should be starting its science
imaging around now!
Friday, July 22
· Last-quarter Moon tonight (exact at 1:02 a.m. Eastern Daylight Time). The Moon rises around the middle of
the night with Jupiter below it. By dawn they're very high in the southeast.
