In this program, We use a number that corresponds to the Moon phase:
| Phase |
Name |
| 0.00 |
Full Moon |
| 0.00-0.25 |
Waning Gibbous Moon |
| 0.25 |
Last Quarter Moon |
| 0.25-0.50 |
Waning Crescent Moon |
| 0.50 |
New Moon |
| 0.50-0.75 |
Waxing Crescent Moon |
| 0.75 |
First Quarter Moon |
| 0.75-1.00 |
Waxing Gibbous Moon |
| 1.00 |
Full Moon (again) |
"Waxing" means growing and "waning" means shrinking.
One appropriate
definition of "gibbous" is "swollen on one side."
Try turning the Simulator on and off to see phases.
Or, try entering the number of the phase in the box.
Notice the solar eclipse at phase 0.50!!!
In reality, the Moon's
orbit is slightly tilted, so solar eclipses are rare, not every month.
Try a phase of 0.5001 for a cool view of an eclipse (be sure to use
Earth View).

Metacom Observatory thanks him for its use.

Satellite
view of Metacom Observatory
This
view of our observatory at Metacom Avenue in Warren, RI USA shows
the surrounding farmland at the North and East [North is at the
top of the photo].
The
Observatory is the 5th building from the north on the left side
of Metacom Avenue which is ends between the two northern most
buildings in the photo. Metacom Observatory is the only building
oriented parallel to Metacom Avenue; all the other buildings are
perpendicular to the street. The Observatory is also the only
building set back from the street.
