Evidence for the evolution and decay of an electrified Medium Scale Traveling Ionospheric Disturbances during two consecutive substorms: First results

Autor: Rathi, R., Sivakandan, M., Chakrabarty, D., Krishna, M. V. Sunil, Upadhayaya, A. K., Sarkhel, S.

Electrified Medium Scale Traveling Ionospheric Disturbances (EMSTIDs) is one of the prominent plasma structures that affect the propagation of high frequency radio waves. Overall, seasonal variation and propagation characteristics of the EMSTIDs are

A rare simultaneous detection of a mid-latitude plasma depleted structure in O($^1$D) 630.0 nm and O($^1$S) 557.7 nm all-sky airglow images on a geomagnetically quiet night

Autor: Patgiri, D., Rathi, R., Yadav, V., Chakrabarty, D., Krishna, M. V. Sunil, Kannaujiya, S., Chaitanya, P. Pavan, Patra, A. K., Liu, Jann-Yenq, Sarkhel, S.

In general, nighttime thermospheric 557.7 nm emission over mid-latitudes is predominantly masked by significantly larger mesospheric component, and hence, F-region plasma structures are rarely observed in this emission. This paper reports the first r

Investigation on the impact of solar flares on the Martian atmospheric emissions in the dayside near-terminator region: Case Studies

Autor: Ram, L., Sharma, R., Rout, D., Rathi, R., Sarkhel, S.

Solar transient events like flares can cause sudden changes in planetary plasma and neutral environment. Here, we present an investigation of the variability of the Martian atmospheric emissions viz. OI 130.4 nm, 135.6 nm, CO2+ ultraviolet doublet (U

Martian M2 peak behavior in the dayside near-terminator ionosphere during interplanetary coronal mass ejections

Autor: Ram, L., Rout, D., Rathi, R., Withers, P., Sarkhel, S.

The interplanetary coronal mass ejections (ICMEs) can pose significant impacts on the Martian ionosphere, resulting in plasma depletion, variability, and escape to space. However, the connections between the ICMEs and the associated responses of the
