Reports Report 7116bx (Event 7116-2021)

Observer
Name Curt M
Experience Level 3/5
Remarks We 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.
