             abstract = "On 21 January 2005, a moderate magnetic storm produced a number of 
                         anomalous features, some seen more typically during superstorms. 
                         The aim of this study is to establish the differences in the space 
                         environment from what we expect (and normally observe) for a storm 
                         of this intensity, which make it behave in some ways like a 
                         superstorm. The storm was driven by one of the fastest 
                         interplanetary coronal mass ejections in solar cycle 23, 
                         containing a piece of the dense erupting solar filament material. 
                         The momentum of the massive solar filament caused it to push its 
                         way through the flux rope as the interplanetary coronal mass 
                         ejection decelerated moving toward 1 AU creating the appearance of 
                         an eroded flux rope (see companion paper by Manchester et al. 
                         (2014)) and, in this case, limiting the intensity of the resulting 
                         geomagnetic storm. On impact, the solar filament further disrupted 
                         the partial ring current shielding in existence at the time, 
                         creating a brief superfountain in the equatorial ionosphere - an 
                         unusual occurrence for a moderate storm. Within 1 h after impact, 
                         a cold dense plasma sheet (CDPS) formed out of the filament 
                         material. As the interplanetary magnetic field (IMF) rotated from 
                         obliquely to more purely northward, the magnetotail transformed 
                         from an open to a closed configuration and the CDPS evolved from 
                         warmer to cooler temperatures. Plasma sheet densities reached tens 
                         per cubic centimeter along the flanks - high enough to inflate the 
                         magnetotail in the simulation under northward IMF conditions 
                         despite the cool temperatures. Observational evidence for this 
                         stretching was provided by a corresponding expansion and 
                         intensification of both the auroral oval and ring current 
                         precipitation zones linked to magnetotail stretching by field line 
                         curvature scattering. Strong Joule heating in the cusps, a 
                         by-product of the CDPS formation process, contributed to an 
                         equatorward neutral wind surge that reached low latitudes within 
                         1-2 h and intensified the equatorial ionization anomaly. 
                         Understanding the geospace consequences of extremes in density and 
                         pressure is important because some of the largest and most 
                         damaging space weather events ever observed contained similar 
                         intervals of dense solar material.",
