Sun Data

Simple module to get the angle of the Sun relative to the Horizon for a given geographic location and datetime. Also allow for the gathering of sunrise and sunset for a given geographical location and datetime, with the option to shift those to general lighting conditions rather than sunset but instead Astro Night, Night for example.

Features

• Angle of Sun for given location and date time
• Get modified datetime for location when sun enters different lighting conditions

Installing

Install using pip into your python virtual environment.

pip install sundata

Usage

Before using sundata to get the lighting information you'll require a location latitude and longitude as well a datetime in order to perform the calculation.

To get only the sunrise and sunset for a given date time the following will be enough.

position = Position(51.772938, 0.102310)
a_date = datetime(2023, 2, 13, 12, 00)
data = SunData(position, a_date)
data.calculate_sun_data()
sunrise = data.sunrise
sunset = data.sunset

To get the lighting periods around sunrise and sunset then a LightPeriod needs to be passed into the calculation method.

pos = Position(51.772938, 0.102310)
current_datetime = datetime(2023, 2, 12, 17, 7)
data = SunData(position, current_datetime)
data.calculate_sun_data(LightPeriod.NIGHT)
sunrise = data.sunrise
sunset = data.sunset

Sunset and Sunrise datetimes have now been shifted to the start of Night and end of Night.
