Observer
NameCurt M
Experience Level3/5
RemarksWe were out looking for northern lights. Seeing frequent shooting stars. Suddenly, the entire area was lit as though someone had turned their headlights on. We were highly startled 😱 Just as our excitement quieted, we heard a clear, bassful thud. We didn't see what we went out to see, but saw something much more memorable.
