A severe magnetic storm was recorded on 29 October 2003, which lasted 22 hours following an X17 flare event on the Sun. The energy released by the Sun took nearly 19 hours to enter the Earth?s magnetosphere resulting in this magnetic storm. Another X10 solar flare occurred in the course of the first magnetic storm. Nearly 20 hours after the second X10 solar flare event, another magnetic storm commenced, noticeably weaker and of shorter duration (13 hours). On November 20, 2008, the largest geomagnetic storm of the solar cycle 23 occurred with Dst index of -422 nT. The geomagnetic storm was generated following a coronal mass ejection (CME) from the active region of the Sun. The extremely large solar eruption on 28 October 2003 caused an intense geomagnetic storm observed on Earth. A second solar eruption on 29 October intensified the storm about a day later. These two events in terms of solar eruption and their resulting effect on the near-Earth environment are investigated. During the course of the second storm some of the strongest substorms in the history of magnetic recordings occurred at Maitri, Indian Antarctic Station. The ground geomagnetic signatures at Maitri during this period are analyzed and compared with the IMF parameters. completed principalInvestigator National Centre for Polar and Ocean Research (NCPOR) 8322525515 voice Headland Sada, Vasco da Gama, Goa 403804 Vasco-da-Gama Goa 403804 IND ictd@ncpor.res.in Dr. Ajay Dhar 20.0 140.0 -90.0 30.0 2004-01-01 2005-12-31 Earth Science-Solid Earth Theme Maitri Antarctic Place Magnetic Storms of October-November 2003 Ground Geomagnetic Signatures from Maitri Project eng TableDigital unknown unknown unknown distributor National Centre for Polar and Ocean Research (NCPOR) +91-832-2525515 voice Headland Sada, Vasco da Gama, Goa 403804 Vasco-da-Gama Goa 403804 IND vssamy@ncpor.res.in Mr. Sakthivel Samy V http://npdc.ncpor.res.in/npdc/search_mf_data.action?search=freeText&expedition_type=all&parameter=MF-1964539789&userType=user&freeTextValue=Magnetic+Storms+of+October-November+2003%3A+Ground+Geomagnetic+Signatures+from+Maitri%2C+Antarctica.
