Cirrus clouds over Curt Gowdy State Park in Wyoming on February 18, 2018.
This was a photo taken on March 9, 2018 in Golden, Colorado. Just north of highway 6, over looking Denver. These are cumulus clouds hanging out over the city, while in the opposite direction a storm front was coming in over the mountains.
If you want to know more about the location or type of clouds, here is a report attached.
Taken at Lost Gulch overlook. Atmosphere is stable, with cirrus fibratus forming below cirrostratus, which creates a halo effect from the sun.

To answer the questions posted by Luke: The timelapse was taken with my iPhone 6+ over the timespan of about a minute and a half, using the iphone’s timelapse feature. I don’t know exactly how much it was sped up, because I wasn’t timing the timelapse with a stopwatch as I watched the storm come in, but that was a mistake because Apple uses “dynamically selected intervals” that they have not, as a company, disclosed the ratio for.
