Selected map type: HMI Magnetogram

View the Sun in multiple wavelengths and imaging modes using current observations from NASA's Solar Dynamics Observatory (SDO). Switch between extreme-ultraviolet AIA views and HMI surface and magnetic-field maps to follow active regions, coronal structure and sunspots.

Solar images are refreshed every hour from the latest available SDO observations.
