possible brilliant sunsets
Over on http://spaceweather.com/ there is a notification that, thanks to the eruptions of Mt. Redoubt in Alaska, the Great Lakes region may be in for interesting sunsets.
It's under "SULFUR DIOXIDE LOOP" which mainly details a ring of SO2 currently approach the west coast but does mention the band approaching the Great Lakes region.
You can see an animation of the event here.
