      • getApproxMoonPositionOnSky

        public static float getApproxMoonPositionOnSky​(Weather.WeatherLocation weatherLocation,
                                               long time)
        Determines the approximate position of the moon on the sky based on rise and set times. Note: to eliminate possible time shifts between rise sets of different days, in most cases this calculation is averaged over three hours.
        Parameters:
        weatherLocation - the location to calculate the value for
        time - the time in UTC (milliseconds)
        Returns:
        the approximate position, where 0 is rise and 1 is set. Returns -1 if the moon is not visible at the time.

        public static float getApproxSunPositionOnSky​(Weather.WeatherLocation weatherLocation,
                                              long time)
        Determines the approximate position of the sun on the sky based on sunrise and sunset times. Note: to eliminate possible time shifts between rise sets of different days, in most cases this calculation is averaged over three hours.
        Parameters:
        weatherLocation - the location to calculate the value for
        time - the time in UTC (milliseconds)
        Returns:
        the approximate position, where 0 is sunrise, 0.5 is midday and 1 is sunset. Returns -1 if the sun is not visible at the time.

        public static boolean usePreciseIsDaytime​(Weather.WeatherLocation weatherLocation)
        Returns if a precise calculation of day/night time with the Astronomy class makes sense. It makes sense between a latutide of -65° to +65°, but not further south or north.
        Parameters:
