Occurrence of equatorial plasma bubbles over Kolhapur
Advances in Space Research, 2014Abstract This paper reports the nightglow observations of OI 630.0 nm emissions, made by using all sky imager operating at low latitude station Kolhapur (16.8°N, 74.2°E and dip lat. 10.6°N) during high sunspot number years of 24th solar cycle. The images are analyzed to study the nocturnal, seasonal and solar activity dependence occurrence of plasma ...

Wind Preparation of the Generation of Equatorial Plasma “Bubbles”
Geomagnetism and Aeronomy, 2019According to theoretical conclusions, zonal western thermospheric winds are the key influence on the generation of equatorial plasma “bubbles.” To verify this assumption, a comparative analysis of the longitudinal distribution of equatorial plasma bubbles and the longitudinal profile of deviations of the zonal western thermospheric wind velocity has ...

Equatorial Plasma Bubble Occurrence Probability with Respect to Month of Year
Геомагнетизм и аэрономия, 2023In this paper, the variations of the equatorial plasma bubble occurrence probability with respectto month of year are investigated. For this purpose, the data obtained on board the ISS-b satellite (~972–1220 km) in the mid−latitude region ±(25°–55°) DIPLAT of the both hemispheres for a year and a half ofthe observations (August 1978–December 1979) were

Equatorial F-Region Plasma Bubbles Studies
5th International Congress of the Brazilian Geophysical Society, 1997Equatorial ionospheric plasma bubbles associated with equatorial range-type spread F, are regions where the plasma densities are much lower than the ambient plasma density and are aligned along the earth's magnetic field lines . The plasma bubbles can be observed by both the radio wave (e.g. ionosonde, radar, scintillation etc.) and optical techniques (

Variability Of Plasma Bubble In The Equatorial Ionosphere At Midnight
Journal of Environmental Extension, 2009There are various types of ionospheric irregularities. Among these is the plasma bubble occurrence. They are most prominent at night time in the equatorial ionosphere. Many of the bubbles drift with approximately the velocity of the background plasma, but it is possible to infer that most bubbles have moved upward at some time in their recent history ...

Statistical Analysis of Separation Distance between Equatorial Plasma Bubbles
2017 IEEE 13th International Symposium on Autonomous Decentralized System (ISADS), 2017Equatorial plasma bubbles in the low-latitude regions can cause loss-of-lock resulting to the availability of ground-based augmentation system (GBAS) due to increased ionospheric gradients. For realistic simulation, distances between adjacent bubbles need to be determined.

Equatorial Plasma Bubbles: Variability of the Latitudinal Distribution with Altitude
Geomagnetism and Aeronomy, 2021Ionosphere plasma irregularities known as equatorial plasma bubbles are the subject of this research. The variability of the latitudinal distributions of the occurrence probability of the bubbles with increasing the observation altitude is studied. For this purpose, the data from the ISS-b (~972–1220 km), ROCSAT-1 (~600 km), and AE-E (~300 km, ~350–475

Observation of equatorial ionospheric plasma bubbles at peninsular Malaysia
2012 International Symposium on Computer Applications and Industrial Electronics (ISCAIE), 2012The research on observation of equatorial plasma bubbles (EPBs) ionospheric at peninsular Malaysia by using Malaysian Real Time Kinematic Global Positioning System Network (MyRTKnet). Plasma bubbles which usually occur during midnight. This determination is made for satellites in Peninsular Malaysia in the September period of 2007 at Universiti Utara ...

Equatorial plasma bubbles at altitudes of the topside ionosphere
Geomagnetism and Aeronomy, 2008A consistent patter, indicating that subtroughs in the He+ density and plasma bubbles can be considered as phenomena of the same origin, has been obtained within the scope of the existent model of equatorial plasma bubbles. The study has been performed based on the measurements of the ISS-b satellite, which flew during the period of high solar activity.
