Usage:

var sun = require('./practical-astronomy/services/sun'); var moon = require('./practical-astronomy/services/moon'); var GeographicCoordinate = require("../models/geographicCoorindate");

const myLocation = new GeographicCoordinate(42.37, -71.05); const myTime = moment();

var riseAndSetTimes = sun.getRiseAndSetTime(myLocation, myTime); console.log('The sun will rise at: ' + riseAndSetTimes.riseTime); console.log('The sun will set at: ' + riseAndSetTimes.setTime);

var moonPhase = moon.getPhase(myTime); console.log('The current moon phase is: ' + moonPhase);
