Ionospheric equatorial plasma bubbles/depletions are plasma density irregularities, which tend to develop under specific conditions during post-sunset hours and continue to evolve non-linearly into the post-midnight period. The Rayleigh–Taylor (Kruskal-Shafranov) instability mechanism is believed to be responsible for the formation of these depletions. An intriguing feature of equatorial...
