Space weather variations can significantly affect ionospheric electron density, which can, in turn, adversely affect various navigational and communication technologies. One such phenomenon is the prompt penetration electric ...

Interplanetary (IP) shocks are known to cause significant modifications in Earth's magnetospheric and ionospheric current systems. The sudden enhancement of solar wind dynamic pressure (PDyn) associated with IP shocks ...

Generally, Co-rotating Interaction Region (CIR) induced geomagnetic storms are weak to moderate in magnitude. Moreover, CIRs can also drive intense storms when they are coupled with an ICME or other interplanetary structures. ...

In this paper, we investigate the characteristics of geomagnetic pulsations (Pi2) using ground magnetometer data from the Induction Coil Magnetometer of Desalpar, Kachchh, Gujarat, India. We report here the morphology of ...

The equatorial plasma bubbles (EPBs) are depleted plasma density regions in the ionosphere occurring during the post-sunset hours, associated with the signal fading and scintillation signatures in the trans-ionospheric ...

This paper highlights the impact of intense solar events over India during 3–20 December 2006. Ionospheric effects of a major solar flare (X9) on December 5 (10:35 UT) have been investigated by using dayside and nightside ...

Geomagnetic storms of G1-class were observed on 3 and 4 February 2022, which caused the loss of 38 out of 49 SpaceX satellites during their launch due to enhanced neutral density. The efects of storm-time neutral dynamics ...

Context : Various high-frequency waves in the vicinity of upper-hybrid and Langmuir frequencies are commonly observed in different space plasma environments. Such waves and fluctuations have been reported in the magnetosphere ...

During geomagnetic quiet conditions, Indian Antarctic stations are considered to be located outside the auroral oval: Maitri (CGM coordinates: 63.3◦S, 54.2◦E) is equatorward and Bharati (CGM coordinates: 74.8◦S, 98.4◦E) ...

The study investigates ion flux variations for the substorms in the inner magnetosphere. The effect of substorm-induced magnetic field dipolarization on the O+ and H+ ion flux is analysed for 22 events from the year 2018 ...
