LYA HV off / OVI voltage at 210, LYA grating position now at 128000 "permanently". UVCS enters SAFE mode at 17:33:41 UT (during DSN gap) due to VLPERR out of bounds. Polarizer Mechanism tested, and UVCS partially recovered as of 19:10 UT at which point, SUMER ramp down, and SOHO Telemetry Submode change must take place. Partial recovery consisted of changing UVCS Software Mode to OPS, moving Polarizer to 8100, 13206, and 2994 Engineering Unit positions, ramping down OVI and VL detector High Voltages (transition to SAFE mode had already turned HV power supplies off), disabling and then reenabling OVI and VL Detector HV commanding, and transmitting OVI, LYA, and VLD science buffers.
