Unique combinations of differently shaped Equatorial Plasma Bubbles occurring within a small longitude range
Listed in National Center for Atmospheric Research
On 12 October 2020 and 26 December 2021, NASA's Global-scale Observations of the Limb and Disk (GOLD) mission observed differently shaped equatorial plasma bubbles (EPBs) simultaneously within similar to 10 degrees longitude, near the subsatellite point and over the Atlantic, respectively which is unusual.
Description
On 12 October 2020, three EPBs with differing curvatures were observed in a similar to 12 degrees longitude sector.
The westside EPB was curved toward 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 similar to 6 degrees adjacent C-shaped and reversed C-shaped EPBs were observed. EPBs' zonal drift velocities at the magnetic equator and both equatorial ionization anomaly 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.
