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 Wednesday that it is visible this Fall. Each date links to an image showing how the Moon will look that evening. The altitude column gives the angle in degrees between the Moon and the horizon at 20:30 (8:30 pm) as seen from Honolulu; small altitudes are more difficult 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.
