The Active Sun from SDO: EUV Variability Experiment (EVE)

Visualizations by Tom Bridgman Released on November 20, 2012
The Solar Dynamics Observatory (SDO) observes the Sun with many different instruments, in many different wavelengths of light. Many of these capabilities are not possible for ground-based observatories - hence the need for a space-based observing platform.

The Extreme Ultraviolet (EUV) Variability Experiment (EVE) measures extreme ultraviolet emission from the solar chromosphere, transition region and corona. This radiation is mostly absorbed in Earth's upper atmosphere and influences Earth's climate.

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. This differences enable scientists to study them more completely, with an eventual goal of improving Space Weather forecasting.
