We report the results of a multi-instrument, multi-technique, coordinated study of the solar eruptive event of 13 May 2005.
We discuss the resultant Earth-directed (halo) coronal mass ejection (CME), and the effects on the terrestrial space environment
and upper Earth atmosphere. The interplanetary CME (ICME) impacted the Earth’s magnetosphere and caused the most-intense geomagnetic
storm of 2005 with a Disturbed Storm Time (Dst) index reaching −263 nT at its peak. The terrestrial environment responded to the storm on a global scale. We have combined
observations and measurements from coronal and interplanetary remote-sensing instruments, interplanetary and near-Earth in-situ measurements, remote-sensing observations and in-situ measurements of the terrestrial magnetosphere and ionosphere, along with coronal and heliospheric modelling. These analyses
are used to trace the origin, development, propagation, terrestrial impact, and subsequent consequences of this event to obtain
the most comprehensive view of a geo-effective solar eruption to date. This particular event is also part of a NASA-sponsored
Living With a Star (LWS) study and an on-going US NSF-sponsored Solar, Heliospheric, and INterplanetary Environment (SHINE)
community investigation.
