Awe man I was so upset to miss these lights the clouds blocked my view. With how active this solar cycle has become and it’s still early on in it. I believe we will be getting quite a few of these maybe one even stronger. When we hit autumn or spring equinox with the way our magnetic fields works any strong solar activity is only amplified around those times. We had a G4 class storm if it was a few weeks prior or later would have possibly been a G3 class
