Ken Murphy is capturing a year’s worth of timelapse sequences from atop San Francisco’s exploratorium – seen above is the first 42 days of his project -
“The earliest day is in the upper left, and consecutive days follow left to right, then down, with the most recent day in the lower right. It starts a little before sunrise, so it’s dark for the first few seconds:
Keep in mind that all of the days are synchronized, so at any given moment, you’re looking at the sky at the exact same time of day for each of the panels. The cascading effect at sunrise and sunset is caused by the variations in day length.”
