The NASA Solar Dynamics Observatory (SDO) mission consists of one sun observing spacecraft with three instruments which is located in a geosynchronous orbit around Earth. The AIA and HMI instruments provide us with solar imagery of unprecedented detail. Below you will find numerous images of the Sun from these instruments in many different wavelengths, revealing many different solar phenomena like solar flares, coronal holes, sunspots and filaments. The numbers on the images below indicate the location of different sunspot groups. If there are no numbers then the Sun is currently devoid of numbered sunspot regions.

A lot of people come to SpaceWeatherLive to follow the Solar activity or if there is a chance to see the aurora, but with more traffic comes higher costs to keep the servers online. If you like SpaceWeatherLive and want to support the project you can choose a subscription for an ad-free site or consider a donation. With your help we can keep SpaceWeatherLive online!
