A look at ~24 hours of the dynamic sun from 5/4-5/5 (13:12 UT to 12:45 UT). The video combines SDO/AIA images from the 304, 171 and 193 angstrom wavelengths. This shows us temperatures ranging from about 40,000 C to 2.5 million C. Bright areas are active regions sitting over sunspots. Loops of hot plasma in the solar corona trace magnetic fields coming from the sunspots lower down in the solar atmosphere. Small brightenings coming from the active regions are solar flares. The giant filament from yesterday still sits intact but with the potential to erupt at any moment or it could remain stable for many days. Some of it will eventually erupt though probably not all of it. Basically, if you look around the sun there is always something happening from large to small scales. The smallest sizes that can be resolved in these images is around 1000 kilometers. credit: NASA/SDO/helioviewer
