Abstract

Julia was observed with the SPHERE instrument (ESO/VLT) around its opposition at eight different epochs. We used ZIMPOL in narrowband imaging mode (N_R filter; filter central wavelength = 645.9nm, width = 56.7nm). Each observational sequence consisted of a series of five images, where each image corresponded to a series of detector integration times (DITs) of 10s, during which Julia was used as a natural guide star for adaptive optics (AO) corrections. Observations were performed under good seeing conditions (<=0.8") with an airmass usually below 1.6. After every asteroid observation, we observed a nearby star for deconvolution purposes to estimate the instrument point spread function (PSF). Finally, standard calibrations, which include detector flat-fields and darks, were acquired in the morning as part of the instrument calibration plan.
