- H3. A total lunar eclipse is observed on December 31. Predict the next lunar eclipse. A total lunar eclipse will occur when the full moon and the nominal orbit of the moon line up together (The solution of two equations). From the following data algebraic equation for the phase of the moon and nominal orbit of the moon can be formed. A new moon (0%) was observed on December 17 and the full moon (10%) was observed on December 31 along with the nominal orbit of the moon (0%). The brimming orbit of the moon (100%) was observed on November 29. When the two equations are equal a lunar eclipse will occur. How many days from December 31 will next lunar eclipse occur? Given the coming year is a leap year - on what dates will the next 4 total lunar eclipses occur?

- The timing of Moonrise is later every day. Let’s understand why: a) Moonrise occurs when you, as you sit on the rotating Earth, turn to the point where you can just see the Moon appear over the horizon. Draw a picture to illustrate what this would look like. Draw the Earth, Moon, and you standing on the Earth to indicate this scenario. (You’ve seen my artistic skills in class, I’m not asking you to do anything better than that. Just label/make clear what is shown). Take this as Day 1.In 24 hours, you would return back to that exact point on the Earth. However, the Moon will also have moved forward in its orbit (it orbits the Earth in the same direction that the Earth is spinning). How far along in its orbit does the Moon move? That is, assume the Moon is orbiting in a circular orbit; in going from Day 1 to Day 2, how many degrees does thee Moon move forward? Indicate (very roughly) via a drawing.b) Because the Moon advanced in its orbit, you now must wait…arrow_forwardGiven the location of Springfield, IL is 40N and 90W, answer the following questions. must explain answer What is the date during a year from which the sun-angle in Springfield starts to increase?
