Operations have resumed at the NASA Solar Dynamics Observatory (SDO) following the flood at its data center in late 2024. In a January 7 update from the Joint Science Operations Center (JSOC) at Stanford, staff said that the observatory has "begun processing most near-real-time (nrt) SDO data products."
The flood occurred on November 26 when a four-inch chilled water pipe broke and caused major flooding in the building. According to a December 9 update, around 20 percent of the database servers and data servers were damaged. According to the SDO, "several large data partitions that are on disk do not function."
The update added that several UPS power supplies were damaged, along with the web servers and the WSO data reduction computer. The machines impacted processed and distributed data from the SDO's Helioseismic and Magnetic Imager (HMI) and Atmospheric Imaging Array (AIA) instruments from the IRIS spacecraft.
