Abstract

Upper atmosphere whorls or vortices produced by an extreme geomagnetic storm were reported for the first time by Evans, Correira et al (2024). Evidence of the vortices was seen in the upper atmosphere’s neutral composition, effective neutral temperature near 160 km, and ionospheric electron densities. Evans, Correira et al (2024) speculated that a combination of GOLD’s unique capabilities and the historical nature of the Gannon Storm allowed for the previously unseen phenomena to be observed. However, following a severe geomagnetic storm on 10 October 2024, evidence of similar upper atmosphere vortices were again observed in GOLD ON2 and TDISK data. The appearance of vortices following another severe geomagnetic storm during solar maximum prompted a review of the GOLD dataset for additional instances, revealing the appearance of vortices following several less intense geomagnetic storms during Solar Cycle 25.
