Mid level solar flare captured in 4K resolution by NASA. Jim Drury reports.
The solar flare was captured by NASA's Solar Dynamics Observatory on April 17. It was released by an active region on the sun's right side, causing moderate radio blackouts. This video was captured in several wavelengths of extreme ultraviolet light, typically invisible to our eyes. NASA colour-coded the images for easy viewing. Solar flares are powerful bursts of radiation - harmless to humans but strong enough to disturb GPS and communications signals.
