SUMER time-series spanning 4 hours (left to right) with the
300 arcsecond slit oriented north-south outside the flaring active
region AR9906. The emission line is from twenty times ionized iron,
at about 10 million kelvin (Fe XXI 1354 Å).
Movie: MPEG showing the slit position and observations, on EIT 195 Å
background.

Caption: You may notice the "unusual" images in this Hot Shot, and that is for a reason: Thanks to the Max Millennium program, a large number of solar observatories, both spacecraft and ground based, focus on certain active regions; the targets are selected by the Max Millennium chief observer for every 24 hour UT period and distributed by email to observatories around the world.
The selection of images above is just to give a "taste" of the vastly different observations that can be combined to pin down the different aspects of large eruptions like this.
