Impact of May 2024 ICME Event on Martian UV Dayglow Emissions using MAVEN/IUVS and EMM/EMUS Observations
Aadarsh Raj Sharma, Vaghamshi Dhruv Dhaneshbhai, Lot Ram +1
We present first near-simultaneous observations of large-scale spatial response of the Martian H Lyman-α and atomic oxygen dayglow emissions (O(3S) 130.4 nm and O(5S) 135.6 nm) du…
Climatology of Mars Topside Ionosphere during Solar Cycles 24 and 25 using MAVEN Dataset of 2015-2024
Lot Ram, Chanchal Singh, Diptiranjan Rout +2
The Mars ambient space environment evolves with the varying solar activity. Understanding the Martian space environment, particularly the topside ionosphere across different phases…
Investigation of Martian UV Dayglow Emissions in the Southern Hemisphere during Solar Quiet-time Conditions: Insights from Multi-year MAVEN/IUVS Observations
Aadarsh Raj Sharma, Lot Ram, Sumanta Sarkhel
The southern hemisphere of Mars possesses concentrated region of strong crustal magnetic fields (CMF), which generate localized magnetic anomalies that can influence atmospheric dy…
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.…
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…
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…
