Quite an amazing photo op for the International Space Station. It captured a fly-over photo of a Russian island volcano. The eruption and plume, just moments earlier, punched through the above cloud strata.
NASA site has a great shot of it along with write up.
APOD has a 3D image of it, for those who might have the red/green glasses around.

That's awesome.
The semicircular cutout in the normal "weather" clouds makes it look as though the heat from the eruption has vaporized the water droplets in those clouds for miles in every direction. That's a hellish way to get a clear sky!
On the ground within that circle, there must have been a lot of radiant heat, even outside the pyroclastic flow area. This reminds me of some of the photos and films I've seen of atmospheric H-bomb tests. This is a very scary eruption. I hope nobody was nearby.

The NASA site says,The eruption cleared a circle in the cloud deck. The clearing may result from the shockwave from the eruption or from sinking air around the eruption plume: as the plume rises, air flows down around the sides like water flowing off the back of a surfacing dolphin. As air sinks, it tends to warm and expand; clouds in the air evaporate. |

Pretty cool picture!
