Volcanic sunsets


The Russian volcano that erupted directly beneath the International Space Station on June 12th is now causing beautiful lavender sunsets across parts of the northern USA and Europe. A plume of ash and sulfur dioxide from the Sarychev Peak eruption is circulating through the stratosphere, and when parts of the plume pass over an area at sunset, the sky can be seen filled with delicate white ripples, sometimes-colorful streamers, and a telltale hue of purple.
