Questions

   Observing_Description: We will observe ADS11300 during Cycle 5 to refine
                          the orbital elements of this close pair now near
                          periastron passage.

Abstract:               We propose to use FGS in TRANS mode to observe the close
                        known binary ADS11300. According to an orbital analysis
                        incorporating recent HST-FGS results, this pair of 54-yr 
                        orbital period is expected to pass through periastron in 
                        1996.25 +/- 0.75 and will reach a component separation 
                        of 10 mas. The proposed observations, in combination with
                        two observations to be secured in Cycle 6, will provide
                        a critical test of the angular-resolution limits achievable
                        with FGS in the TRANS mode.
