    -Earth Radiation Budget Satellite 
    -Study of Earth's radiation budget and stratospheric aerosol gases.
    This satellite can be seen as a heritage of Space Shuttle Challenger. It was
    deployed in 1984 during mission STS-41-G by Sally Ride, well-known as the
    first American woman in space, just one year earlier. The satellite used an own
    Orbit Adjust Propulsion System (OAPS) to move to its operating orbit after
    deployment from the Shuttle. Originally intended to have a 2-year operational
    live, it finally just retired in 2005 for butgetary reasons.
    Earlier attempts to photograph the satellite during a series of morning-passes
    in June, failed to resolve more then a small speck. It seems to be a hard object 
    in less then optimal passes, even at considerable imagingscales. The latest 
    attempt on August 24 during a favorable almost 80 degrees evening-pass succeeded 
    to capture a well-defined shape. The images can be interpreted to show a body and 
    solar panels seen from a certain observingangle as most frames show comparable 
    structure. Presented are 2 of the best ones. Exact interpretation however is 
    difficult to determine.
