Stationkeeping Burn Today

Today at 2200 UTC (6 pm ET) SDO will execute a stationkeeping burn. This 2.4 second firing of four thrusters keeps SDO within its longitude limits of its assigned geosynchronous orbit. Science data will be unavailable for about an hour to allow the spacecraft to prepare for the burn, fire the thrusters, and recover from the burn.
