We've done several posts on social media pointing at photos taken around sunset and twilight. Here are some of those pics and a screenshot of Skyclock.
As we've always said, this isn't new information, but for many, it's presented in a way that is easy to understand and an example of data visualization. In other words, at some point during the day we decided to go to the park at sunset to take some pictures, checked Skyclock, and went at that time.
Check Skyclock in the App Store and Google Play.
