Polarimetry
(submitted 19 Sep)
We currently have 3 observations in polarimetry (more coming).
Two from the Calern Observatory in France (Ph. Bendjoya, J.-P. Rivet). Those were obtained yesterday night and last night.
One from the VLT (S. Bagnulo, S. Ieva; NEOPOPS project) obtained yesterday night.
The main result is that FA22 polarization looks similar to S or X-type objects polarization. However, we notice that it is displaying a slightly larger polarization than previously observed object in these groups which might hint toward a low albedo.
Our first analysis of the polarization suggests that FA22 albedo should be 0.17 (+0.05-0.04) leading to a diameter of 140 (+20-30)m taking into account the H = 21.78
