The carrier from STEREO Behind was detected once again by the DSN during the morning of September 10. During 3 brief TWTA sampling periods, the carrier signal had a lower peak signal of -166 dBm and a period of ~60 seconds continuously. Subcarrier lock did not occur. While the uplink can support short critical commands, the downlink cannot support telemetry. The spacecraft was configured for a low power mode by powering off all power switching boards and loads. EA mode was enforced as to prevent the use of the HGA in C&DH standby mode.
