idea: use sun elevation to calculate brightness

This is some code to show the sun elevation over the course of 3 days.

import datetime

from astral.geocoder import database, lookup
import astral.sun
import matplotlib.pyplot as plt
import pytz

location = lookup("Amsterdam", database())
now = datetime.datetime.now(tz=pytz.timezone("Europe/Amsterdam"))
times = [
    now.replace(minute=minute, hour=hour, day=day)
    for day in range(1, 3)
    for hour in range(0, 24)
    for minute in range(0, 60)
]
angles = [astral.sun.elevation(location.observer, t) for t in times]
plt.plot(times, angles)

I get that. I’ve started to look at the math on this, I’ll post anything I can figure out.

I am also trying to determine how to integrate a more natural circadian cycle.

I haven’t had a lot of time to really get into the physics/math so as of now it’s over my head.
