All astrometric flares show clockwise motion in the plane of the sky with a period of around an hour, and the polarization vector rotates by one full loop in the same time. Given the apparent similarities of the flares, we present a common fit, taking i","authors_text":"A. Amorim, A. Drescher, A. Eckart, A. Foschi, A. Kaufer, C. Straubmeier, D. C. Ribeiro, D. Lutz, E.
