SDO Offline

[SDO]

Last night at 0551 UTC (0152 a.m. ET), as SDO began the scheduled roll calibration maneuver, the ACS went into Sun-acquisition mode. SDO remains in that mode while the engineers look for the cause. The spacecraft is stable and in contact with the SDO MOC. Science data is not being taken at this time. Updates will be posted when available.
