Viewing the Moon

Even a small telescope can reveal an enormous amount of detail on the surface of the Moon.


This table provides simulated images and other data for the Moon every Monday that it is visible this semester. The dates link to images showing how the Moon will appear that evening. The altitude column gives the angle in degrees between the Moon and the horizon at 20:30 HST (8:30 pm) as seen from Honolulu; large altitudes are easier to observe. The diameter column gives the Moon's angular diameter, measured in minutes of arc. The phase column indicates the angle of sunlight in degrees.
