Since the intensity and beauty of any given Sunrise and Sunset involve many factors such as level and density of cloud cover, smoke or haze drift, etc, etc, etc. It would be novel to have some kind of predictor. Just a thought.
What an amazing job you do. I Love, Love, Love your 1-hour forecasts!
None the less I am not complaining but rather just letting you know, although I'm sure you already do. Thank you for all you do.
