[FG] Magnetic Reconnection in the Magnetosphere

This session will focus on kinetic physics in day- and night-side reconnection. With the recent launch of the Magnetospheric Multiscale (MMS) satellites, there is already a wealth of new data on kinetic scale physics. Scene setting talks to frame relevant questions and generate discussion will include particle acceleration in dayside reconnection (Allison Jaynes, CU-Boulder) and how global/non-local physics impacts kinetic reconnection physics (John Dorelli, NASA-GSFC), both of which will include discussion of MMS data. Other speakers on dayside reconnection are (in no particular order) Joo Hwang, Sun Hee Lee, Richard Denton, Jan Egedal, Rishi Mistry, Kris Maynard, and Cong Zhao. In addition, we will have a discussion of magnetotail stability, with a scene setting talk on recent progress (Slava Merkin, JHU-APL). Other speakers on magnetotail reconnection are (in no particular order) Yongliang Zhang, Stefan Kiehas, Haoming Liang, Misha Sitnov, Andrei Runov, Joachim Birn, Phil Pritchett, and Tony Lui.
