CORONAGRAPH OBSERVATIONS AND ANALYSES OF THE ULTRAVIOLET SOLAR CORONA Semiannual Status Report 1 April 1987 through 31 March 1989

摘要

The technical activities have been very demanding. Following the preliminary integration activity at GSFC in 1986, several improvements were made to the instrument that will result in enhanced scientific performance or in regaining a capability that had deteriorated during the delay time in the launch date. It has been necessary to replace several devices which degraded during the delay time. The replacement effort has proven to be time consuming.
