    Solar wind interaction with small bodies .2. What can Galileo's detection of magnetic rotations tell us about Gaspra and Ida

    , D1 Symposium of COSPAR Scientific Commission D, at the 30th COSPAR Scientific Assembly, Pages: 59-68

    As the Galileo spacecraft passed the asteroids Gaspra in 1990 and Ida in 1993, the magnetometer recorded changes in the solar wind magnetic field that we associate with the presence of the nearby body. This paper focuses on the types of interactions that can produce perturbations in the solar wind. We have suggested that the interaction at Gaspra is consistent with expectations of flow diversion by a magnetic dipole moment and an associated ''magnetosphere'' whose scale size is much larger than the diameter of the solid body. The conditions for the Ida flyby leave more room for ambiguity. The observations could plausibly be related to either interaction with a magnetized body or with a conducting body. We will report on details of the observations that may enable us to distinguish between the different types of interaction and to provide quantitative estimates of the physical properties of the asteroids themselves.

    Ion measurements in the Jovian magnetosphere by the Ulysses EPAC experiment: A comparison between dawn and dusk sectors

    , D1 Symposium of COSPAR Scientific Commission D, at the 30th COSPAR Scientific Assembly, Pages: 183-186

    We report on results from the EPAC experiment on board the Ulysses spacecraft during the Jupiter Flyby in February 1992. We compare ion anisotropies (E = 0.24-0.77 MeV/N) received on the inbound pass in the noon sector at low magnetic latitudes with those from the outbound pass in the dusk sector at high magnetic latitudes. The results can be summarized as follows: (1) The classification of an inner and middle magnetosphere is observed inbound at low magnetic latitudes as well as outbound at high magnetic latitudes. (2) Three-dimensional anisotropies of ions in the noon sector were found in the corotation direction with radial components, whereas in the dusk sector field aligned anisotropies as well as anisotropies in corotation and anti-corotation were observed. (3) The steady increase of He/O with increasing latitude in the inner magnetosphere suggests the ionosphere as an internal He-source. (4) We find a difference in the He/O-ratio between the day- and the dusk side of the magnetosphere.

    Galileo flybys of Earth: The nature of the distant shock

    , D1 Symposium of COSPAR Scientific Commission D, at the 30th COSPAR Scientific Assembly, Pages: 197-204

    We report on observations of the Earth's bow shock at unprecedentedly large downtail distances, some as remote as 360 R(E). Surprisingly, we find that even at these large distances, the bow shock signature remains clear. The cases we report are among the weakest shocks ever clearly identified. These shocks reveal patterns of field changes remarkably similar to those observed for stronger shocks. Indeed, several of the shocks could serve as textbook examples because they occur in unusually quiet and steady solar wind conditions. The quasiperpendicular shocks are, in some cases preceded by whistler wave trains. Several of the shocks which have normal vectors in the transitional region between quasiperpendicular and quasiparallel are associated with large amplitude wave disturbances in the downstream plasma. Although low Mach number, these shocks are the source of large amplitude turbulence. We show a range of fits to the locations of the shock crossings, and argue that, for steady solar wind conditions, there is no sign of tail flapping. The displacement of the shock from the tail axis appears to be governed by the interplanetary magnetic field orientation as previously reported for Venus.
