12.3 the Moon: Phases, Eclipses, and the Tides
12.3 The Moon: Phases, Eclipses, and the Tides 1. The Motions of the Moon a. Rotation i. Period of Moon’s rotation = 27.3 days b. Revolution (orbit) i. Period of the Moon’s orbit around the Earth = 27.3 days ii. Lunar cycle = 29.5 days (time that the calendar month is based on) 1. Time needed for the moon to return to the same place in the sky 2. Since the Earth is orbiting as well as the Moon, the Moon needs the extra 2 days to “catch up to the Earth” in its orbit c. Orbital period of the moon = the rotational period of the moon = 27.3 days i. Synchronous rotation ii. Reason that we only see one side of the Moon 2. Phases of the Moon a. Order of the phases i. Based on the Moon appears to us on Earth ii. New moon, waxing crescent, 1st quarter, waxing gibbous, full moon, waning gibbous, 3rd/last quarter, waning crescent b. The sun’s light moves from right to left across the face of the moon c. Moonrise and moonset i. Time when one’s location on Earth can see the moon 3. Eclipses a. Any time one celestial body passes between another celestial body and the Sun b. Lunar eclipse i. Partial lunar eclipse; when the any part of the Moon falls within the penumbra (partial shadow) of the Earth ii. Total lunar eclipse; when the Moon falls entirely within the umbra (total shadow) of the Earth c. Solar eclipse i. Partial solar eclipse; when any point on the Earth falls within the penumbra (partial shadow) of the Moon ii. -

Introduction The Air Almanac was originally intended for air navigators, but is used today mostly by a segment of the Celestial navigation requires accurate predictions of the maritime community. In general, the information is similar to geographic positions of the celestial bodies observed. These the Nautical Almanac, but is given to a precision of 1' of arc predictions are available from three almanacs published and 1 second of time, at intervals of 10 minutes (values for annually by the United States Naval Observatory and H.

Its precision is far greater than that required by navigation stars. celestial navigation. Even if the Astronomical Almanac is The Multi-Year Interactive Computer Almanac used for celestial navigation, it will not necessarily result in (MICA) is a computerized almanac produced by the U.S. more accurate fixes due to the limitations of other aspects of Naval Observatory.

Naked-Eye Observations of the Moon (See Also Take-Home Exp
TAKE-HOME EXP. # 3 Naked-Eye Observations of the Moon (See also Take-Home Exp. #4 which can easily be done at the same time as this one.) You have already seen what the Moon looks like in its various phases, but you may not realize it can be "out" in the day as well as the night. Nor are most people familiar enough with the geometry of the Sun-Moon-Earth system to draw it as easily as you will be able to by the end of this experiment. a. When to make observations of the moon's phases: nytime you can find the Moon, make an observation. These observations do not have to occur only at the principal phases. Anytime and anywhere you can see the Moon is a good time to make a sketch and record the requested information. b. Dates of the Principal phases of the Moon, Times of Moonrise, and Moonset: Earth When doing this experiment, check your newspaper New Moon everyday for the times of moonrise and moonset; they are listed on the weather page. Many calendars show the days of occurrence of the principal phases--new, first- 1st Qrtr quarter, full, third quarter--of the Moon. Most newspapers have the principal phase dates listed every day. In the view of Earth pictured to the right, the Moon’s orbit is the circle, and incoming sunlight is from the right. Full The Moon moves counterclockwise around the Earth, taking 28 days to complete its cycle. Starting at the topmost diagram, a “New Moon” phase, seven days elapse between each succeeding diagram. -
Key Stage 2: Daytime Moon Viewing
Key Stage 2: Daytime Moon Viewing Teacher’s Notes Curriculum Links: Unit 5E Earth, Sun and Moon, Unit 3F Light and Shadows This extension activity uses daytime viewing of the Moon (during school hours) to reinforce ideas learned in the classroom about light, shadow and the Moon itself. Equipment: Magnetic compass, notepads and pencils for students. Optional: Set(/s) of binoculars, monoculars or telescopes for closer observation of the Moon, cameras. Class discussion before the activity: How can we see the Moon? Answer: The light from the Sun reflects off the Moon and into our eyes or our telescopes. Reflections are how we see most things on a day-to-day basis. Sunlight also reflects off the planets and that is how we see them. Stars, like the Sun are light sources, while other objects are not. Draw the Moon and Earth on the board as shown below, but with no shaded halves. The curved arrows represent the way the Moon orbits the Earth (viewed from a top-down perspective) and the straight arrows represent the light coming from the Sun. Ask students to copy the diagram and shade in the bits of the Earth and Moon that are in darkness, where the Sun’s light does not reach. Some students may ask how the light of the Moon can get to the Earth in the previous diagram. The orbit of the Moon is tilted with respect to Earth’s orbit around the Sun – the diagram on the next page will help students visualise what is happening. Is the Moon ever completely dark? Answer: No. -
Phases of the Moon
TA Guide for Notes Phases of the Moon Description In this activity, students stand around a bright light bulb in an otherwise dark room, holding a styrofoam ball at arm’s length. As they turn around, they watch the changing pattern of light and dark on the styrofoam ball which reproduces the phases of the Moon. Then, using a second ball as the Earth, students explore the geometry of the Sun-Earth-Moon system to predict the rise and set times of different phases of the Moon. The students “accidentally” stumble onto the alignment of the Sun, Earth and Moon during lunar and solar eclipses. Learning Goals After this tutorial, together with lecture materials, students should be able to • use the geometry of the Sun, Earth and Moon to illustrate the phases of the Moon and to predict the Moon’s rise and set times • illustrate the geometry of the Sun, Earth and Moon during lunar and solar eclipses, and explain why there are not eclipses every month Set-up 20 minutes The students will work together in groups of 3. In order to fit enough groups of students, you may need to use 2 light sources (shown at right). Set up one in the center of the lab and, if necessary, one in the center of the reading room (push the tables to the inside around the light. This will stop the students from getting too close to the light and messing up the geometry.) When both lights are needed, both TAs will be “A” TAs that lead the activity to their own groups of students. -

Station Profile: WCOL/Columbus, OH ACM Camp's Dual Impact
May 21, 2018, Issue 602 Station Profile: WCOL/Columbus, OH More than 65% of iHeartCountry stations saw gains with Per- sons 25-54 over the winter, according to format captain Rod Phil- lips, and the company’s WCOL/Columbus, OH enjoyed some of the most impressive. The station was up 25% year over year in that demo, and continues to post enormous numbers 6+. WCOL averaged an 11.9 over the last 13 PPM surveys, in fact, the highest being April’s 14.4. It was ‘COL’s best overall showing since PPM arrived in the market. The Columbus powerhouse has always been successful, but the last few months have been especially notable. PD Dan Zuko, who’s heading into his 20th year with the station and fifth at its helm, Rod Phillips attributes WCOL’s success to a seasoned and involved staff, increased concert traffic and a potent music cycle.

Moon Project Pictures
Ian Spangenberg Popular Astronomy Club September 2019 Go to this link and type in your city: ◦ https://www.timeanddate.com/moon/ This website provides the rise, meridian, and set times for the Moon. ◦ Moonrise: when the Moon just comes up over the horizon – you will probably be able to see the Moon 10 minutes or so after this time if you aren’t surrounded by tall trees (if there are no obstructions on your horizon). ◦ Moonset: when the Moon sets below the horizon. ◦ Meridian: without getting into a bunch of complex concepts, it is basically when the Moon is up highest in the sky. This will be the best time to view the Moon, but anytime between Moonrise and Moonset would be great. The link on the previous page also provides information about ◦ Rise/set times for the Sun and planets ◦ Eclipses ◦ Moon phases (but I have a different website for those) ◦ Time and time zones Last quarter is also known as 3rd Quarter One side of the moon is always illuminated.
