This is a few months old, but worth noting:
A photographer and die-hard solar observer has captured absolutely stunning views of a colossal filament of super-hot plasma snaking its way across the surface of the sun.
If you can’t do something with this for your Call of Cthulhu or other horror campaigns then… I dunno. Have a sandwich and get a good night’s sleep, maybe? The campaign – or, more disturbing, background filler – writes itself.
