Handling the Moon

insgen considers the moon in the scheduling of requests. For simplicity, the coordinates and phase of the moon are calculated only at midnight.

The moon will not be a factor if any of the following are true:

• insgen is run with the nomoon option
• the current phase of the moon is less than the MoonPhase specified in the request
• All of the targets in the request are farther away than the number of degrees specified in the request by the MoonDistance
• UTStart or SunStart are used to schedule the request

If none of the above is true the VISIBLE window is trimmed by any time that the moon is above the horizon. If the remaining time is too short to perform the observation a notation in the Skipped table is made.
