Momentum Management Maneuver #30 today, 1925-2000 UTC

SDO will perform Momentum Management (Delta-H) Maneuver #30 today. From 1925-2000 UTC (3:25-4:00 pm ET), SDO science data may be missing or incomplete. These maneuvers are used to manage the reaction wheel speeds on the spacecraft and are a normal part of our operations.
