| Abstract: | Observations at the reconnection site from the Magnetospheric Multiscale mission are used to examine the occurrence of magnetic reconnection along the magnetopause in relation to both the upstream interplanetary magnetic field (IMF) orientation and local magnetosheath variations. While there is a statistically larger number of reconnection intervals observed downstream of the quasi‐parallel bow shock than is accounted for based on the histogram of overall IMF orientations, it is surmised that increased fluctuations downstream of the quasi‐parallel bow shock cause greater large‐scale motion of the magnetopause surface; but do not preferentially enhance the occurrence of steady magnetic reconnection. An examination of the locations of observed reconnection sites relative to model predictions also suggest that enhanced magnetosheath fluctuations do not result in steady reconnection occurring at random locations at the magnetopause. Key Points: Magnetospheric Multiscale (MMS) encounters the magnetopause reconnection site over a wide range of external conditionsThe occurrence of reconnection region encounters is consistent with that of large‐scale magnetopause motion, and depends on interplanetary magnetic field orientationDistributions of MMS locations with respect to model reconnection line predictions are independent of region downstream of the bow shock [ABSTRACT FROM AUTHOR] |
