On 29 July 2000, IMAGE EUV observed a shoulder-like bulge on the plasmapause. Goldstein et al. <2002> showed that plasmaspheric shoulders may be caused by a pre-dawn concentration of eastward overshielding electric (E) field triggered by a decrease in magnetospheric convection. A simulation by the Magnetospheric Specification Model (MSM) captures the shoulder formation, reproducing its approximate size and location. ROCSAT-1 ion drift meter data are consistent with the strength, time development and local-time variation of the MSM eastward penetration E-field (and associated radial flows) during the shoulder formation on 28 July. |
