Momentum Management Maneuver #20 is Today

SDO will execute Momentum Management Maneuver #20 today from about 1915-1945 UTC (3:15-3:45 p.m. ET). This Delta-H burn is used to keep the reaction wheels within their speed limits. During the maneuver the science data is usually not valid as the spacecraft moves around.

We are looking forward to eclipse season starting August 29, 2014, giving us another opportunity to see the Earth's limb against the Sun. Eclipse season ends September 21, just in time for a lunar transit on September 24 from 0650-0720 UTC (2:50-3:20 a.m. ET).A station-keeping maneuver will happen on September 3, 2014, at 2245 UTC (6:45 ET).
