The Variation of Resonating Magnetospheric Field Lines with Changing Geomagnetic and Solar Wind Conditions

We would like to acknowledge some very helpful conversations with T. Elsden, I. J. Rae, and C. Forsyth. S. J. W. was supported by NERC StudentshipNE/L002493/1. T. K. Y. was supported by STFC Grant ST/H002480/1 and NERC Grant NE/K011766/1. M. K. J. was supported by STFC Grant ST/H002480/1. J. K. S. was supported by STFC Grant ST/N000722/1 and NERC Grant NE/P017185/1. The authors would like to thank the IMAGE magnetometer team for providing the data. The data are available at http://space.fmi.fi/image/beta/ website. The OMNI solar wind data are publicly available from the NASA Space Physics Data Facility, Goddard Space Flight Center (http://omniweb.gsfc.nasa.gov/ow.html). This research used the SPECTRE High Performance Computing Facility at the University of Leicester.
