AB: By design, the SuperDARN network provides multipoint observations of magnetospheric phenomena. It provides observations over the majority of the high-latitude region, with observations in the northern hemisphere from Finland westward through to Alaska, and at latitudes ranging from Wallops Island to the magnetic pole, with conjugate observations over a similar range in the southern hemisphere. In addition, because the network has been in operation for several years, it is now possible to examine magnetospheric phenomena statistically. This paper uses the SuperDARN database in conjunction with a list of substorm onsets determined from the IMAGE satellite [Frye et al., 2004] to examine the relationship between substorm onset locations and features of the convection pattern. Particular attention is devoted to the latitude of onset locations compared to the latitude of the near-midnight convection reversal boundary. Because of this focus, the set of observations examined is limited to cases where SuperDARN provided sufficient observations in the midnight sector to determine the latitude of the convection reversal.
