NASA’s Solar Dynamics Observatory has released a video showing a filament eruption on August 31st.
The video shows all the action in dramatic detail in extreme ultraviolet light, with the red Sun segment covering almost 3 hours.
The NOAA spaceweather prediction center estimates that a cloud of radiation from the eruption will reach Earth today. But fear not, the radiation cloud will only create a minor to moderate geomagnetic storm.
Long filaments like this one have been known to collapse with explosive results when they hit the stellar surface below.
