That’s right, rocket scientists, weather spacecraft have seen the erupting Grímsvötn volcano in Iceland and it’s pretty cool. This one’s from Meteosat-9:

The animation shows Meteosat-9 observations from the High Resolution Visible (HRV) channel, providing measurements with a resolution of 1 km at the sub-satellite point, representing roughly a 3-5 km resolution over Iceland. At around 19:15 UTC, a very rapid eruption of the Grímsvötn volcano occurred, which is visible from the animation below. The eruption is transporting a large amount of water vapour and ash significantly higher than the cloud deck heights over Iceland.

Meteosat-9 is located on the Greenwich Meridian, while the GOES-13 spacecraft, also a weather observation satellite, is located at 75º West. So here we have a different angle…
