25. Have you ever seen a halo around the Moon
Have you ever seen a halo around the Moon? This fairly common sight occurs when high thin clouds containing millions of tiny ice crystals cover much of the sky. Each ice crystal acts like a miniature lens. Because most of the crystals have a similar elongated hexagonal shape, light entering one crystal surface and exiting through the opposing surface refracts 22 degrees, which corresponds to the radius of the Moon Halo. A similar Sun Halo may be visible during the day. The picture was taken in Lansdowne, Pennsylvania, USA. Exactly how ice-crystals form in clouds remains under investigation.

30. Misconception #2 True or False.
The moon rises and sets at the same time each day.
false

31. Misconception #3 True or False. The moon is never out during the day.

33. Watch again, but pick a feature on the moon and track it over the phases

35. Sooooooooooooooooo……………………….. What causes the phases of the Moon?

36. Why does the moon appear bigger when it is rising?
Because the horizon provides scale, something to “measure” size with. In the sky, there is no scale.

37. How big of a shadow does the moon cast?
The umbra is roughly ~100 miles wide, but the penumbra can be ~1000 miles. The umbra will only cover 1% of Earth’s surface.

38. How many eclipses are there in a year?
There are approximately 2 lunar eclipses a year and 1-2 solar eclipses in a year.

39. More practice Assigned partners this time.
One partner gets a moon sphere, the other the E-W signs.
Calmer behavior than yesterday or we’re done and back to book only work.
Leave your stuff. I will lock the door.

47. This vintage 60-kopek stamp celebrates a dramatic achievement
This vintage 60-kopek stamp celebrates a dramatic achievement. On the 7th of October, 1959, the Soviet "Luna 3" successfully photographed the far side of the moon giving denizens of planet Earth their first ever view of this hidden hemisphere. Lacking the digital image technology familiar now, Luna 3 took the pictures on 35mm film which was automatically developed on board. The pictures were then scanned and the signal transmitted to Earth days later in what was perhaps also the first interplanetary fax. In all, seventeen pictures were received providing enough coverage and resolution to construct a far side map and identify a few major features. Depicted on the stamp are regions dubbed the Sea of Moscow, the Soviet Mountains, the Bay of Astronauts, and the Sea of Dreams.
