6.3 Closest Approach Results

The closest approach region of the G2 encounter encompasses the time interval between 18:55:51 to 19:05:00 UT. Figures 6.54 and 6.55 show three field line tracings for three typical adsorption features observed by Galileo for model M1 and model M2, respectively. Of course, there are many more features present in the closest approach region; these embody the characteristics of them all. Each rate profile presents a loss cone adsorption for the ions and electrons, with the electrons also exhibiting loss cones in the anti-moon direction. Not all energy channels for these two features are presented here in Chapter 6. Table 6.10 gives information and some details on the plots not shown here; they are included in Appendix C.

Figure 6.54 Model 1 inbound field line tracings. The time in UT is indicated at each feature location.
