Abstract
Low-latitude boundary layer (LLBL) can be found at low latitudes on magnetospheric flanks and it covers the whole dayside magnetosphere. In spite of its crucial role in the solar wind---magnetosphere coupling, basic LLBL parameters and their relations to upstream conditions are still under debate.
We analyze in details Themis multipoint observations of one multiple LLBL passage with motivation to determine sources of observed transients. The data are compared with predictions for flux transfer events (FTE), upstream pressure pulses, and surface magnetopause waves.
Although these processes exhibit many common signatures, a careful analysis can undoubtedly distinguish among them.
