This data set contains Calibrated data taken by the New Horizons Alice Ultraviolet Imaging Spectrograph instrument during the KEM1 ENCOUNTER mission phase. This is VERSION 3.0 of this data set. This data set contains data acquired by the spacecraft between 08/14/2018 and 07/31/2019. It only includes data downlinked before 08/01/2019. Future datasets may include more data acquired by the spacecraft after 08/13/2018 but downlinked after 07/31/2019. This dataset contains data from Arrokoth's encounter.

This data set contains raw and partially processed data from observations of Magellan radio transmissions while the signal was passing through the solar corona. Scintillations on the signal can be related to structure and motion of the coronal material [WOO1993]; polarization of the signal can be used to infer magnetic field within the plasma. Data were acquired using stations of the NASA Deep Space Network (DSN). The Magellan spacecraft transmitted signals that were 100 percent linearly polarized at 13 cm and right-elliptically polarized at 3.6 cm. During summer 1992, when Magellan was in solar superior conjunction, the spacecraft came within 0.6 solar radii of the Sun's center when viewed from Earth.
