Speckle observations of the binary asteroid (22) Kalliope with C2PU/PISCO

ABSTRACT We present new speckle measurements of the position of Linus, the satellite of the asteroid (22) Kalliope, obtained at the 1 m Centre Pédagogique Planètes et Univers-Epsilon telescope on the Plateau de Calern, France. Observations were made in the visible domain with the speckle camera Pupi...

Zusammenfassung:	ABSTRACT We present new speckle measurements of the position of Linus, the satellite of the asteroid (22) Kalliope, obtained at the 1 m Centre Pédagogique Planètes et Univers-Epsilon telescope on the Plateau de Calern, France. Observations were made in the visible domain with the speckle camera Pupil Interferometry Speckle camera and COronagraph. We obtained 122 measurements in February–March 2022 and April 2023, with a mean uncertainty close to 10 milliarcsec on the angular separation.
