INFO:
The far-side image display the seismic signature of magnetic activity on the side of the Sun that we cannot directly see from Earth. Darker regions indicate locations where there is an accumulation of magnetic field.

Active Regions


Active regions (JSOC/Stanford)

This page automatically reloads the latest magnetogram every 2 minutes
INFO:
The image shows the full-disk line-of-sight magnetic fields from the Solar Dynamics Observatory. Active regions are automatically detected and tracked during their passage over the solar disk. Each active region is enclosed in a box called a HARP (HMI Active Region Patch).

Corona


Solar corona (SDO/NASA)

Info:
Solar flares are seen as bright regions in images observed by AIA onboard SDO. The intense electromagnetic radiation causes low frequency and HF communication problems.

Corona


Solar corona (SOHO/NASA/ESA)

Info:
Coronal mass ejections (CME).
CMEs are seen as large plasma clouds in coronagraph images observed by LASCO onboard SOHO.
The small white circle shows the size of the solar disk.
