Abstract:
Magnetic reconnection at the Earth’s magnetopause is the primary process by which solar wind plasma and energy gains access to the magnetosphere. One indication that magnetic reconnection is occurring is the observation of accelerated plasma tangential to the magnetopause. This work describes an initial examination of the direction of accelerated ion flows along the magnetopause surface as observed by the Hot Plasma Composition Analyzer (HPCA) instruments on board the recently launched Magnetospheric Multiscale (MMS) set of spacecraft. The accelerated flow directions are compared with the predicted location of magnetic reconnection at the magnetopause using convected solar wind observations in conjunction with the Maximum Magnetic Shear model.
