Take on a Moon Observing Challenge from the Astronomical League. This activity challenges you to complete each of the following tasks:

  • Do an outreach activity. This could be an International Observe the Moon Night event or any activity that encourages observing the Moon in general.
  • Observe the Moon with just your eyes. No equipment is required.
  • Estimate the Moon's percent illumination. Not illuminated at all would be 0%, half-illuminated would be 50%, and completely illuminated would be 100%.
  • Make a sketch or capture an image of the Moon that includes at least ten of the features below. Indicate your chosen features on your sketch or image:
    • Mare Crisium
    • Mare Fecunditatis
    • Mare Frigoris
    • Mare Imbrium
    • Mare Nectaris
    • Mare Nubium
    • Mare Serenitatis
    • Mare Tranquillitatis
    • Crater Copernicus
    • Crater Tycho
    • Crater Rays from Crater Copernicus
    • The Woman in the Moon
