Date/Time of Initial Impact: August 6, 2019 1849Z

Date/Time of Expected End: TBD

Length of Event: 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 6-August-2019 starting at 18:49:38Z over land. There will be an expected change of +8.77 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.
