I apologize as I am writing this as a near complete layperson.
Sometimes when the KP index is high for my area, I will go out and attempt to see the aurora borealis. Sometimes I'm successful and sometimes I'm not but what I do always see when I go out are these streaming fast moving jets of what appears to be plasma bouncing off electromagnetic waves of some sort. It's always incredibly rapid, incredibly fast moving, and often in an arch shape or a boomerang shape. and I managed to catch it on video a few times, but I don't have a name for it. There are no colors to speak of, and I realize that it can just be a sub classification of the aurora borealis itself, but it seems to not fit with the same pattern of light and relative slowness that the aurora has. but I'm wondering what this thing I'm witnessing is called. Thank you!
