Speckle Observations With PISCO in Calern (France): III. Astrometric Measurements of Visual Double Stars in 2019 and New or Revised Orbits for STT531 AB, STT77 AB, STF1338 AB, COU1746, STT260, A1109 AB, HU1291, and A632 AB

Astronomische Nachrichten, EarlyView.
ABSTRACT We present relative astrometric measurements of visual double stars, made in 2019 with the speckle camera PISCO at the 1‐m Epsilon telescope of the C2PU facility (Observatoire de la Côte d'Azur, Calern site). Our observing list contains orbital couples as well as double stars whose motion is still uncertain.
