Purple Sunset
Volcanoes are pretty amazing things.
A while back there were two big eruptions in the North Pacific - one in Alaska, one in the Kuril Islands. You've all seen the picture from the ISS of the Kuril eruption, with its ash cloud, shockwaves and pyroclastic flows. The dust from those eruptions went high into the stratosphere, eventually blanketing much of the Northern Hemisphere.
That's why we've had some spectacular sunsets recently, with a distinct lavender-purple tinge, much like this one from early July here in Putney.
