Which NASA spacecraft, launched in 2010, monitors the Sun in multiple wavelengths?

NASA’s Solar Dynamics Observatory monitors the Sun in multiple wavelengths.

Launched on 11 February 2010, SDO is a NASA mission in the Living With a Star program. Its purpose is to study how the Sun’s magnetic field forms, changes, and releases energy into space as solar flares, solar wind, and energetic particles.

SDO observes the Sun continuously using three main instruments. The Atmospheric Imaging Assembly photographs the solar atmosphere in several ultraviolet and extreme-ultraviolet wavelengths; the Helioseismic and Magnetic Imager maps the Sun’s magnetic field and interior motions; and the Extreme Ultraviolet Variability Experiment measures changes in the Sun’s ultraviolet output.

A common mix-up is confusing SDO with SOHO, STEREO, or Solar Orbiter. Those are also solar missions, but SDO is the NASA observatory launched in 2010 specifically associated with high-resolution, multi-wavelength monitoring from geosynchronous Earth orbit. It can produce roughly 1.5 terabytes of data each day.
