  1. ; ; ; ; (, Journal of double star observations)
    Freed, R; Harshaw, R; Genet, Russell M (Ed.)
    We have taken astrometric measurements of three star systems: WDS 00033+5332 A 1500 AB,C, WDS 05283+0358 HJ 2266, and WDS 19557+3805 DAM 1 AB. We used the Las Cumbres Observatory telescopes to take images of these star systems, and we then analyzed them using Afterglow Workbench. For WDS 00033+5332, we found the position angle to be 81.62° ± 0.45° and an angular separation of 9.01’’ ± 0.04’’. Based on our analysis, we were not able to determine whether the WDS 00033+5332 double is physical. For WDS 05283+0358, we found the position angle to be 37.58° ± 0.15° and an angular separation of 7.29’’ ± 0.04’’. It is already known that WDS 05283+0358 is a physical double, and our new data supports this claim. For WDS 19557+3805, we found the position angle to be 234.64° ± 0.63° and an angular separation of 6.89’’ ± 0.10’’. Our new data points suggest this system is gravitationally bound
