SOHO Shuts Down Again

[10 Jan 2000] According to NASA: “As of Friday 7 January 2000 at 00:28 UT, SOHO is in Emergency Sun Reacquisition (ESR) mode. Since the entry into ESR happened during a scheduled gap in the contact with the spacecraft, the event was not detected until a while later. A spacecraft emergency was declared at 02:16 UT, to ensure adequate Deep Space Network (DSN) coverage with 34-meter antennas.”

NASA is still investigating the cause of this latest glitch in SOHO operations. SOHO had been functioning normally up until the time that it went into ESR mode. NASA expects to have the spacecraft in normal operating status later today or tomorrow.
