A year of sunsets (2006 version)

Flickr has a lot of sunset photographs. Too many, some would say.


To build this graph I collected just a few of them, by searching for photos that have been tagged “Sunset”.


I collected only 100 photos from the hundreds posted each day of the preceding 365 days, so that the photos are evenly distributed across the past year. There are over 35,000 photos shown in the graph.


I positioned each photo horizontally according to the day it was taken, and vertically according to the hour it was taken.


By making each photo translucent, I created a “hot spot” which shows when the most photos were taken, each day of the past year.


The bright band shows the approximate time of sunset for each day. You can see that as the year progresses, the time of the sunset changes.


The deepest dip in the band corresponds to the summer solstice (about June 22), and the highest part of the band corresponds to the winter solstice (about December 22).


This is the second time I’ve graphed the curve of the sunsets using Flickr sunsets. The first time, over a year ago, I used all the photos then available, which produced a more inconsistent looking graph.
