Outage at the Stanford, JSOC is Offline

A cooling water line burst in the Stanford building housing the SDO HMI JSOC yesterday. Several inches of water were in the JSOC room. As of this morning it appears the flooding has been drained but things are still wet and at least one leak onto electronic equipment continued. An initial assessment is that the water affected many systems but did not provide a time for return to service.

The JSOC is currently offline while the damage is assessed and repaired. The SDO data will be stored at the DDS in New Mexico until the repairs are complete and then will be automatically delivered to the JSOC.

This means that all HMI and AIA data from the JSOC will be unavailable until repairs are completed, the JSOC restarted, and the data delivery from the DDS re-established. Science data will be produced several days after that. Near-realtime data from before 26 Nov 2024 will continue to be available on the SDO wenbsite.

We appreciate your understanding, and are grateful for the dedication and responsiveness of the Stanford team.
