Unraveling the Generation Mechanism of a Mid-Latitude Plasma Blob and the Evidence of Its Rare Interaction with a MSTID Phase Front
D. Patgiri, R. Rathi, V. Yadav +10
We report observations of two distinct nighttime F-region irregularities, plasma blob (localized density enhancement) and medium-scale traveling ionospheric disturbance (MSTID), in…
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) dur…
Automatic Characterization of Mid-latitude Multiple Ionospheric Plasma Structures from All-sky Airglow Images using Deep Learning Technique
Jeevan Upadhyaya, Satarupa Chakrabarti, Rahul Rathi +5
The F-region ionospheric plasma structures are propagating high and or low electron density regions in the Earth ionosphere. These plasma structures can be observed using ground ba…
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…
Evidence of potential thermospheric overcooling during the May 2024 geomagnetic superstorm
Alok Kumar Ranjan, Dayakrishna Nailwal, MV Sunil Krishna +2
During intense geomagnetic storms, the rapid and significant production of NO followed by its associated infrared radiative emission in lower thermosphere contributes crucially to…
Evidence for the evolution and decay of an electrified Medium Scale Traveling Ionospheric Disturbances during two consecutive substorms: First results
R. Rathi, M. Sivakandan, D. Chakrabarty +3
Electrified Medium Scale Traveling Ionospheric Disturbances (EMSTIDs) is one of the prominent plasma structures that affect the propagation of high frequency radio waves. Overall,…
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,…
