A case study on the impact of interplanetary coronal mass ejection on the Martian O(1S) 557.7 nm dayglow emission using ExoMars TGO/NOMAD-UVIS observations: First Results
Aadarsh Raj Sharma, Lot Ram, Harshaa Suhaag +6
We report, for the first time, the impact of an interplanetary coronal mass ejection (ICME) on the recently discovered O(S) 557.7 nm dayglow emission in the Martian atmosphere.…
Seasonal variation in nighttime NO radiative cooling as observed by TIMED/SABER in lower thermosphere during solar maximum and solar minimum
Alok Kumar Ranjan, MV Sunil Krishna, Akash Kumar +2
Both composition and temperature play a crucial role in determining the NO radiative cooling in lower thermosphere as observed by TIMED/SABER. In this work, we present a detailed i…
Impact of solar wind disappearance event on the Martian nightside ionospheric species: First results
L. Ram, D. Rout, S. Sarkhel
The impact of a rarest solar wind phenomenon [disappearing solar wind (DSW) event during 26-28 December 2022] on the Martian nightside ionosphere is investigated, for the first tim…
A rare simultaneous detection of a mid-latitude plasma depleted structure in O(D) 630.0 nm and O(S) 557.7 nm all-sky airglow images on a geomagnetically quiet night
D. Patgiri, R. Rathi, V. Yadav +7
In general, nighttime thermospheric 557.7 nm emission over mid-latitudes is predominantly masked by significantly larger mesospheric component, and hence, F-region plasma structure…
Investigation on the impact of solar flares on the Martian atmospheric emissions in the dayside near-terminator region: Case Studies
L. Ram, R. Sharma, D. Rout +2
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 atmosph…
Martian M2 peak behavior in the dayside near-terminator ionosphere during interplanetary coronal mass ejections
L. Ram, D. Rout, R. Rathi +2
The interplanetary coronal mass ejections (ICMEs) can pose significant impacts on the Martian ionosphere, resulting in plasma depletion, variability, and escape to space. However,…
