Ionospheric response of St. Patrick’s Day geomagnetic storm over Indian low latitude regions The current work shows the ionospheric response to an intense geomagnetic storm known as St. Patrick’s Day storm which occurred from 17-22 March 2015 using the ionospheric Chaurasiya, Sunil; Patel, Kalpana; Kumar, Sanjay; Singh, Abhay; Published by: Astrophysics and Space Science Published on: YEAR: 2022 DOI: 10.1007/s10509-022-04137-3 |

The results presented in this paper are obtained from low-latitude ionospheric total electron content (TEC) variation during the chosen geomagnetic storm events happening during the solar cycle 24. We include the four intense geomagnetic storms that occurred on 26 September 2011, 15 July 2012, 19 February 2014 and 20 December 2015, depending upon the availability of TEC data. For this, we have used the TEC data from low-latitude station Varanasi (geographic latitude 25°, 16′N, geographic longitude 82°, 59′E and geomagn ...

This study investigates the ionospheric Total Electron Content (TEC) responses over 75°E longitude to the solar flares and geomagnetic storms of September 6–9, 2017. The results of this study provide the impacts of solely solar flares on the ionosphere and such impact when the effects of solar flares and geomagnetic storm are combined. On September 6, two X class solar flares, namely X2.2 at 0857 UT and X9.3 at 1153 UT, were recorded with quiet geomagnetic conditions. The EUV/X-ray intensity of X9.3 flare was significan ...

Radiative cooling due to NO at 5.3 The effect of geomagnetic storms on the peak emission of NO Volume Emission Rate (NO VER) at 5.3 m, in mesosphere and lower thermosphere (MLT) region, is studied over the Asian sector during 26\textendash29 September 2011 (storm 1) and 18\textendash21 February 2014 (storm 2). The data for peak emission of NO VER is obtained from SABER instrument onboard the NASA\textquoterights TIMED satellite. The SABER retrieved data along with the neutral densities obtained from NRLMSISE-00 model have been used to study the latitudinal ...
