Flashing lights over Nova Scotia, Canada. Filmed earlier this month.
Witness report: Dad and I saw these lights flashing back and forth today (enjoy the live commentary). We didn’t notice the other flashing light to the right until watching this video. They continued to flash rapidly until eventually blinking at the same time and fading out to the left.
When I slowed the video down I noticed a pattern from left to right – red, white, white, red,… Checked flight radar – no helicopters and only one plane around. I live in a pretty rural area with not a lot of air traffic.
