Unique Combinations of Differently Shaped Equatorial Plasma Bubbles Occurring Within a Small Longitude Range Journal Article uri icon

Overview

abstract

  • On 12 October 2020 and 26 December 2021, NASA’s Global-scale; Observations of the Limb and Disk (GOLD) mission observed differently; shaped EPBs simultaneously within ~10o longitude, near; the subsatellite point and over the Atlantic, respectively which is; unusual. On 12 October 2020, three EPBs with differing curvatures were; observed in a ~12o longitude sector. The westside EPB; was curved towards the east, in a C-shape. The middle was straight. The; eastside EPB was curved westward, in a reversed C-shape. In the second; case, 26 December 2021, in a smaller longitude range of; ~6o adjacent C-shaped and reversed C-shaped EPBs were; observed. EPBs’ zonal drift velocities at the magnetic equator and both; EIA crests were compared. These occurrences of oppositely shaped EPBs; simultaneously in a narrow longitude may indicate that small-scale; longitudinal variations in the E-region density, electric field, neutral; wind variations, or a combination of them were present.
