This movie is generated for a wavelength of 335 Ångstroms (33.5 nanometers) which highlights a spectral line of iron that has lost 15 electrons (also known as iron-16 or Fe XVI) at temperatures of 2,500,000 K. These images show active regions in the corona.
This visualization is one of a set of visualizations (others linked below) covering the same time span of 17 hours over the full wavelength range of the mission. They are setup to play synchronously on a Hyperwall, or can be run individually.
The images are sampled every 36 seconds, 1/3 of the standard time-cadence for SDO. This visualization is useful for illustrating how different solar phenomena, such as sunspots and active regions, look very different in different wavelengths of light. These differences enable scientists to study them more completely, with an eventual goal of improving Space Weather forecasting.
