     abstract = "{This study reports an extreme ionospheric plasma depletion event over
        the Eastern Pacific from postmidnight to early morning during
        the superstorm's recovery phase on 21 November 2003 observed by
        the DMSP F13, ROCSAT-1, GRACE, and CHAMP satellites, and two
        ground-based GPS receivers. The depletion and its
        interhemispheric geomagnetic conjugate effect occurred between
        {\ensuremath{\sim}}40{\textdegree}S and 40{\textdegree}N
        geomagnetic latitudes. This suggests a possible extremely long-
        range flux tube connection with an apex altitude exceeding 6,000
        km over the geomagnetic equator. Notably, the observed altitude
        for midlatitude depletions of equatorial origin in the morning
        is the highest ever reported. Previous studies have primarily
        observed the extension of equatorial plasma bubbles to middle
        latitudes in the post-sunset hours. The continuous upward
        vertical plasma drift, supported by ROCSAT-1 and TIE-GCM
        simulations, may drive the unprecedentedly strong latitudinal
        extension of these midlatitude plasma depletions in the
        midnight-to-morning sector.}",
