摘要
We present AO observations of Io before the satellite went into eclipse, and while it was in Jupiter's shadow. For the sunlit images Io itself was used as the wavefront reference source, while nearby Ganymede was used as reference 'star' when Io was in eclipse. Observations were obtained in Kp, Lp, and Ms bands. We show results before and after deconvolution of the data. We determined the flux densities for the hot spots from the original Io-in-eclipse data via a FFT method, and from the sunlit images after deconvolution of the images with MISTRAL. We present preliminary temperatures and areal coverages for the 6 brightest volcanoes.
