On June 7, 2011, an M-2 flare occurred on the Sun which released a very large coronal mass ejection (CME). In this view in visible light seen by the SDO/HMI instrument, we can't even see the event. This view is provided as a comparison to how dramatic the event appears in extreme ultraviolet light, as seen in 3838 (304 Angstroms), 3839 (171 Angstroms), and 3840 (211 Angstroms), near ultraviolet light, 3841 (1700 Angstroms), presented a much less impressive event.
