The Night Sky
Friday, September 12
Auroras tonight? And possibly Saturday night? A coronal mass ejection from the
Sun hit the Earth around 8 this morning Eastern Daylight Time (12:00 UT), and
another arrived a few hours later. They were not as strong as expected, but their
effects may continue for more than a day. See our article: Potent Solar Flare —
Auroras Friday?. And check for recent photos.
In the southwestern sky at dusk, Antares, Mars, and Saturn now form an almost
equally spaced straight line, as shown at right. Mars continues to move east
against its starry background. Watch for it to pass ½° north of Delta Scorpii on
September 17th and 3° north of Antares on the 27th and 28th.
This evening one of Saturn's moons, 10th-magnitude Rhea, will occult (cover up) a
much brighter star, 7.8 magnitude SAO 159034, for much of eastern North
America. Details and illustrations are in our article, See Saturn’s Moon Rhea Hide
a Star.
Saturday, September 13
How soon after sunset can you make out the big Summer Triangle? Vega, its
brightest star, is nearly at the zenith (for skywatchers at mid-northern latitudes).
Deneb is the first bright star to Vega's east-northeast. Altair shines less high in the
southeast.

Sunday, September 14
If you have a dark sky and a scope that can reach 13th-magnitude galaxies, here's an observing project you've probably never
thought of: Steve Gottlieb's "Going Deep" tour of Vorontsov-Velyaminov galaxy pairs now high in the evening sky. See the
September Sky & Telescope, page 60, with charts and pictures.
Monday, September 15
Last-quarter Moon (exactly last-quarter at 10:05 p.m. EDT). The Moon rises around midnight tonight under the horn-tips of
Taurus. It stands high in the south over Orion by Tuesday's dawn.
Tuesday, September 16
Arcturus is the bright star fairly high due west at nightfall. It's an orange giant 37 light-years away. Off to its right in the
northwest is the Big Dipper, most of whose stars are about 80 light-years away.
