Unexpected Rainbows (Part 13)
Correspondent Alan Garde pointed me to this cool unexpected rainbow at Spaceweather (you will have to scroll down to see it, but a high resolution image is here). Not only has the glass of the bus stop acted as a prism to produce a spectrum, but you can also see the Fraunhofer lines in the spectrum.
I've never seen this before, maybe you need a particular intensity of spectrum to see them, but I'm going to be scrutinizing unexpected rainbows very closely now.
