Tomorrow morning there is a cluster of bright objects in the eastern sky — one moon, one star and three planets. The highest is Venus, and between that planet and the moon is the bright star Regulus. To the lower left of the moon are Mars and then Mercury.
The International Space Station makes a high bright pass in the morning sky. The space station starts off at 6:41 a.m. 10 degrees above the northwest horizon. Three minutes later the ISS has moved almost directly overhead. The spacecraft will continue across the sky, but will become more difficult to see as it moves into the brightening sky. By 6:47 a.m. the ISS is 10 degrees above the southeast horizon.
Since the new moon occurs tomorrow, it will not be in the sky tonight. In Sagittarius is a bright cluster of stars known as the Sagittarius Cluster. To find it, first locate Mars in the south-southwest. Just over 2 degrees to the upper left of Mars is the star cluster. Using binoculars you can see a fuzzy glow. This is a group of 80,000 stars that orbit on the outside of our Milky Way galaxy.
The International Space Station is visible in the sky this morning again. At 6:33 a.m. the spacecraft is 10 degrees above the west-northwest horizon. It slowly climbs higher in the sky, reaching a peak of 32 degrees above the southwest horizon at 6:36 a.m.
Early this evening the thin crescent moon is near the planet Jupiter. At 8 p.m. the pair are located about 5 degrees above the horizon, and will set before 9 p.m.
The autumnal equinox occurs this afternoon at 3:01 p.m. Thus today, the sun is directly overhead at the equator, and day and night are approximately equal in length.
Tonight the International Space Station makes a bright but brief pass through the sky. At 8:34 p.m. the space station is 10 degrees above the south-southwest horizon and near the stinger of Scorpius. The ISS disappears at 8:36 p.m.
