Date/Time Issued: August 13, 2018, 1440Z

Product(s) or Data Impacted: Jason-3 Operational Geophysical Data Records (OGDRs) )

Date/Time of Initial Impact: August 19, 2018 17:34:48Z

Date/Time of Expected End: TBD

Length of Outage: Any impact to products would be 30 minutes before and up to 2 hours following the maneuver.

Details/Specifics of Change: A Jason-3 maneuver is scheduled for 19-August-2018 starting at 17:34:48Z. There will be an expected change of around +10 m in the semi-major axis possibly resulting in large radial orbit errors in the OGDRs. Over any ocean points, this will affect the sea surface height, but not the wind and wave content in the products.
