| Remarks | About 1 minute after the bright light flashed like lightning there was a single boom just like a thunderclap that rattled things for a split second. I couldn't really see the angles of the flash at the start or the end, because I was inside the house, but near an open window. So discount my "angles" measurement. I am a weather nut, so even though I knew there was no chance of rain or thunder, I quickly glanced at radar on computer and saw no echoes. Then I thought it must have been a transformer blowing, but I knew it couldn't be that. Then within 30 minutes I looked at the "Nelson, BC" Facebook post and saw they were already soliciting reports from people who heard the boom and saw the flash. |
