I was at my Blissa (lush type) Base where it never storms, never even rains, working on cooking up ingredients and managing my ridiculously overstuffed inventories an ship/exocraft hold, when I noticed what seemed to be lightning flashes.
It kept on going throughout the daylight and into the night and was really bugging my eyes. By the time I finished up there I was starting to get a headache. So I went outside to investigate.
The whole sky was glitching out in strange 3D flashes. Sometimes it looked like giant grey cabinets over the whole sky, then it would flash white and disappear only to have some other band of strangeness flash in and obscure even the planetary rings.
I tried to capture it but only video would do it justice --especially since the sound effects were awesome. I logged out before the sky-wide flickering and flashing elicited a migraine.
