This post is an MMBASIC program for the MicroMite eXtreme that can be used to determine rise and set conditions of the moon relative to an observer anywhere on the Earth.

Here's a typical user interaction with the software and several rise/set conditions computed by this computer program.

rise and set of the moon
========================

please input the calendar date

(month [1 - 12], day [1 - 31], year [yyyy])
< for example, october 21, 1986 is input as 10,21,1986 >
< b.c. dates are negative, a.d. dates are positive >
< the day of the month may also include a decimal part >

? 3,16,2017

please input the geographic latitude of the observer
(degrees [-90 to +90], minutes [0 - 60], seconds [0 - 60])
(north latitudes are positive, south latitudes are negative)
? 39,40,36

please input the geographic longitude of the observer
(degrees [0 - 360], minutes [0 - 60], seconds [0 - 60])
(east longitude is positive, west longitude is negative)
? -104,57,12

please input the altitude of the observer (meters)
(positive above sea level, negative below sea level)
? 1644

please input the number of days to simulate
? 5

Yes.

It's the location of the Chamberlin Observatory on the University of Denver campus.

I've added the calculation and display of the moon's phase to the moon_riseset.bas MMBASIC program.

Here's the link to the zipped archive with the new source code.
