Hey @mariannewest this was actually Space X it was a launch that took place from Vandenberg Air Force Base in Lompoc California we also saw it from Morro Bay, was said to you could see it pretty much anywhere on the California coast, and at the same time I a little bit right before Japan actually launched a rocket it's pretty amazing to see though. That cloud was from the burnoff.
