Incredible Solar Flare, Prominence Eruption and CME Event (hydrogen alpha filter)

  • Released Wednesday, June 27, 2018

On June 7, 2011, an M-2 flare occurred on the Sun which released a very large coronal mass ejection (CME).

This view filtered for the hydrogen-alpha spectral line is collected from ground-based observatories operated by the National Solar Observatory (NSO). This view is provided as a comparison to how dramatic the event appears in extreme ultraviolet light, as seen in 3838 (304 Ångstroms), 3839 (171 Ångstroms), and 3840 (211 Ångstroms), near ultraviolet light, 3841 (1700 Ångstroms), presented a much less impressive event.
