Subject: general-announcement
Impact: data-unavailable
Detail: HRPT switching zone drift. Risk of interruption. The Metop-A satellite is currently in drifting orbit. As a consequence the geographical zones, defined to control the switching times of the satellite HRPT system, are drifting westwards at a rate of 0.02 degree per day. Users near the borders of switching zones might experience small changes in their acquisition times of the HRPT signal. On-board timings will be updated approximately every 8 months to compensate for the drift geolocation. A dedicated announcement will be issued in advance of each of these updates.[Rev-2]: Update the Event End date.

Detail: NOAA have announced a GOES-16 (GOES-EAST) SEISS MPS-LO Electron and Ion Microchannel Plate (MCP) HV Bias Calibration from 16 November 1800z to 17 November 2030z. The calibration will consist of 2 hours of commanding followed by a 24.5 hour power off of the MPS-LO Deflection Electrode High Voltage (required for performance data collection). SEISS MPS-LO will experience data degradation during this 26.5 hour period until the Deflection Electrode High Voltage is powered back on returning the sensor to nominal operation. The SEISS MPS-LO Calibration will be cancelled due to Critical Weather Day or if the Space Weather environment is not appropriate for the calibration.
