The Fall 2011 eclipse season for the Solar Dynamics Observatory spacecraft started on September 11, 2011. The Solar Dynamics Observatory has eclipse seasons twice a year near each equinox. For three weeks our orbit has the Earth pass between the Observatory and the Sun. The current eclipse season started on September 11 and lasts until October 4. The new photo shows the first eclipse from SDO’s Fall 2011 eclipse season. In the picture, the glowing orb of the sun is partially blocked by the dim shadow of Earth in between the spacecraft and the star.
According to scientists these eclipses can last up to 72 minutes in the middle of an eclipse season. Two antennas near Las Cruces, N.M. are dedicated to round-the-clock reception of data from the spacecraft, which is managed at NASA’s Goddard Space Flight Center in Greenbelt, Md..
