Science Buddies: "Ask an Expert"

Hello everyone. I need help of someone smarter than me on the topic from the title. Now, I know that ground level auroras are implausible, but I touched the topic in this SF story I am writing, and now l'm in the search of mechanism that would explain such things, in the frame of SF story of course. Any ideas?

Hi Reverend,

This forum is intended for students who are doing a science fair project for school. My guess is that by "SF" you mean you are writing a science fiction story. It's great that you are trying to to have realistic scientific explanations for things in your story (as you learn more about science, you'll quickly find that many movies and books fail to do that!) but unfortunately this isn't really the right place to ask.
