|
|
# Example Python program for Astronomy Engine:
|
|
# https://github.com/cosinekitty/astronomy
|
|
#
|
|
# This program calculates sunrise, sunset, moonrise, and moonset
|
|
# times for an observer at a given latitude and longitude.
|
|
#
|
|
# To execute, run the command:
|
|
|
|
# python3 riseset.py latitude longitude [yyyy-mm-ddThh:mm:ssZ]
