Fritz Benedict CoI_Institution: University of Texas Contact: Questions Observing_Description: We will observe GL623 during Cycle 6 to determine its parallax and the orbit of the faint companion. VISITS ARE MORE IMPORTANT THAN REFERENCE STARS, SO FEEL FREE TO CHOP STARS OFF THE ENDS OF VISITS TO FIT INTO AN ORBIT. All visits are scheduled to occur during times of maximum parallax factors. Real_Time_Justification: Calibration_Justification: Abstract: We will observe GL623 4 times during Cycle 6. When added to the observations secured during Cycles 4 and 5, we will obtain a precise parallax, barycentric orbits, and accurate masses of this star and its faint, low-mass (possibly sub-stellar) companion.
