Currently, SDO data servers are offline while the damage is assessed and repaired. This means that all HMI and AIA data from SDO will be unavailable until repairs are completed and the pipeline is restarted, and thus no data from SDO past 2024-11-26 will be shown on the Solar activity pages.

The operational data in the graph above has been modified to remove the scaling factor that has been applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor in the operational data, flare indices for the operational data were reported as 42% smaller than for the science quality data. The scaling factor has also been removed from the solar flare list to reflect the true physical units.
