Something burning through the sky?
I spotted this in south America. Take a look.
Not 'in the sky' but yes, it's burning. Good spotting.
Given the area I suppose one might call it a 'jungle fire' rather than a 'forest fire' though. The colors are as one would expect. Orange would be hotspots with flame, the white coloration is smoke drifting away, and the dark area in the center is burnt jungle/forest.
There's another couple of fires burning to the NW, to which I'm including a placemark.
