1 1 Moon Features

2 2 Phases of the Moon The Moon orbits the Earth ~ every month. The Moon appears to have different phases because we see more or less of the lighted side of the Moon depending on where it is with respect to the Sun.

3 3 First Quarter Phases of the Moon Waxing Gibbous Waxing Crescent Full Moon New Moon Waning Gibbous Waning Crescent Flash Applet Last Quarter

4 4 Phases - Photos

5 5 Apps for Learning Moon Rise and Set Times Horizon apps The Earth s rotation determines your horizons Your horizons and the Sun determine local time Use the local time and your horizons to determine rise and set time for any phase Very helpful University of Nebraska app that shows sunlight coming from left, but doesn t draw horizons

6 6 Rotation of the Moon We only see one side of the moon Moon rotates at the same rate as it orbits the Earth P P spin orb When spin and orbital periods are correlated = synchronous orbit

7 7 Rotation of the Moon

8 8 Moon -- Part of Far Side

9 9 Eclipses (supplemental topic not on exam) Umbra = darkest shadow of an object. Sun completely blocked in umbra Penumbra = lighter shadow Sun only partially blocked Umbra Sun E Penumbra

10 10 Eclipses Solar eclipse = when the Earth passes through the shadow of the moon Lunar eclipse = when the Moon passes through the shadow of the Earth

11 11 Total Solar Eclipse Sun completely covered by the moon -- seen only in the umbra Umbra Sun E Penumbra View from the Earth

12 12 Partial Solar Eclipse Partial Eclipse: Part of Sun is blocked by the Moon -- only seen in penumbra Umbra Sun E Penumbra View from the Earth

13 13 Annular Solar Eclipse Moon too far from Earth to cover Sun completely -- umbra does not reach the Earth Umbra Sun E Penumbra Umbra does not touch the Earth View from the Earth

14 14 Solar Eclipse

16 16 Total Solar Eclipse August 21, 2017 The previous total solar eclipse over the coterminus 48 states was the eclipse of February 26, 1979 which passed over the northwestern states of Oregon, Washingon, Idaho, and Montana. The August 21, 2017 eclipse sweeps across the United States from Oregon to South Carolina, allowing almost every person in the 48 states to reach totality within a day s drive. THE MOON'S SHADOW IN IDAHO: On Aug.21st during the Great American Solar Eclipse, an Earth to Sky space weather balloon floating 26 km high snapped this picture of the Moon's shadow blacking out a 70-mile-wide patch of terrain in Idaho.

17 17 August 21, 2017, Mayview, MO Eclipse totality photographed from Mayview, MO by Carolyn Menningen. Sony ILCE-5100, 4 sec exposure at f/22, ISO speed 100, f = 210 mm lens. The horizon during totality was quite bright, as we were 12.4 miles from the edge of the shadow and 22.7 mi from its center. Totality lasted 2 minutes and 2 seconds where we stood in a rural cemetary. Photo by Ken Menningen, taken with an ipad Air 2.

18 18 August 21, 2017, Moore Springs, WY Eclipse totality photographed from Moore Springs, WY by Alyssa Likeness. Longer exposure to emphasize corona detail at 1 to 2 solar radii above the photosphere. Eclipse totality photographed from Moore Springs, WY by Alyssa Likeness. Shorter exposure to emphasize inner corona, with prominences visible at the upper right.
