2017 Solar Eclipse  - Mysterious Shadow Bands
Channel: World Explorer
Date: 2018-07-08

2017 just before the eclipse we used a high-speed camera to film shadow bands. Best viewed in max resolution! Scientists still don't fully understand what these are. They appear as thin wavy lines of alternating light and dark that can be seen moving and undulating in parallel on plain-coloured surfaces immediately before and after a total solar eclipse. Shadow bands have been noted throughout history, but are highly difficult to record--more so due to video compression! This was just north of Idaho Falls.
