With a peak negative excursion of Sym\u2010H below \u2212500\u00a0nT, this storm is the second largest of the space era. Solar wind energy transferred through radiation and mass coupling affected the entire Geospace. Our study revealed that the dayside magnetopause was compressed below the geostationary orbit (6.6 RE) for continuously \u223c6\u00a0hr due to strong Solar Wind Dynamic Pressure (SWDP). Tremendous compression pushed the bow\u2010shock also to below the geostationary orbit for a few minutes. Magnetohydrodynamic models suggest that the magnetopause location could be as low as 3.3RE. We show that a unique combination of high SWDP (\u226515\u00a0nPa) with an intense eastward interplanetary electric field (IEF\n                    <jats:sub>Y<\/jats:sub>\n                    \u00a0\u2265\u00a02.5\u00a0mV\/m) within a super\u2010dense Interplanetary Coronal Mass Ejection lasted for 409\u00a0min\u2013is the key factor that led to the strong ring current at much closer to the Earth causing such an intense storm. Severe electrodynamic disturbances led to a strong positive ionospheric storm with more than 100% increase in dayside ionospheric Total Electron Content (TEC), affecting GPS positioning\/navigation. Further, an HF radio blackout was found to occur in the 2\u201312\u00a0MHz frequency band due to strong D\u2010 and E\u2010region ionization resulting from a solar flare prior to this storm.\n                  <\/jats:p>","DOI":"10.1029\/2024sw004126","type":"journal-article","created":{"date-parts":[[2024,11,28]],"date-time":"2024-11-28T01:20:56Z","timestamp":1732756856000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":136,"title":["Super\u2010Intense Geomagnetic Storm on 10\u201311 May 2024: Possible Mechanisms and Impacts"],"prefix":"10.1029","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9530-6752","authenticated-orcid":false,"given":"S.","family":"Tulasi Ram","sequence":"first","affiliation":[{"name":"Indian Institute of Geomagnetism  Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.","family":"Veenadhari","sequence":"additional","affiliation":[{"name":"Indian Institute of Geomagnetism  Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7832-8669","authenticated-orcid":false,"given":"A.
