A composite of 9 still frames from OSPAN in H-alpha (656.3 nm) shows a tsunami-like wave spreading from a white-light flare erupting from AR 10930. Numbers indicate the date and time in Universal Time. Note that the brightness and contrast have been enhanced to bring up details of the tsunami. Credit: NSO/AURA/NSF and USAF Research Laboratory.
