Abstract

Separation ( $\rho$ ) and Position Angle (PA) measurements are reported of 10 pairs which measures where last reported in the WDS +20 years from epoch of observation 2021.066. Measurements were obtained by direct imaging and are presented with associated measurement uncertainties, as well as, comparisons to measurements determined from Gaia DR2 & EDR3 and historic data extrapolation at epoch of J2000.0.
