TL;DR
This paper reports speckle observations of the binary asteroid (22) Kalliope and its satellite Linus, providing precise positional measurements that enhance understanding of its orbital characteristics.
Contribution
First speckle measurements of Linus's position around Kalliope using the PISCO camera at C2PU, improving orbital data accuracy.
Findings
122 measurements obtained with ~10 mas uncertainty
Improved orbital parameters for Linus around Kalliope
Demonstrated effectiveness of speckle imaging for asteroid satellites
Abstract
We present new speckle measurements of the position of Linus, the satellite of the asteroid (22) Kalliope, obtained at the 1m C2PU-Epsilon telescope on the Plateau de Calern, France. Observations were made in the visible domain with the speckle camera PISCO. We obtained 122 measurements in February-March 2022 and April 2023, with a mean uncertainty close to 10 milli-arcseconds on the angular separation.
