Skywatch September 19-25: Harvest Moon arrives Monday night | Local News

Sunday: The International Space Station makes a low pass over the northern sky this evening. The space station starts 10 degrees above the west-northwest horizon at 8:52 p.m. When the spacecraft reaches its climax two minutes later, it will be in the Big Dipper bowl 15 degrees above the north-northwest horizon. The ISS disappears just under 10 degrees above the northeast horizon at 8:57 p.m., when the station enters Earth’s shadow.

Monday: The full moon occurs tonight at 6:54 p.m. The full moon in September is known as the Harvest Moon. The harvest moon is the full moon that occurs closest to the fall equinox. It is called the Harvest Moon because with the light of this moon, farmers can work late at night during the peak of their harvest.

Tuesday: Half an hour after sunset, the planet Mercury remains a difficult planet to find. To find Mercury, you will need binoculars and a clear horizon to the west-southwest. Slowly scan the horizon and Mercury will appear.

Wednesday: Today is the last day of summer, because the start of tomorrow morning marks the end of summer and the beginning of fall. The equinox occurs at 2:21 p.m., when the Sun is directly over the equator, and day and night are roughly equal in length. The Sun will continue to move south across our skies towards the Tropic of Capricorn as we progress into the fall.
