Brief Description (Abstract):

A series of solar eruptions occurred during October-November 2003 resulting in severe magnetic activity observed on Earth during this period. 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.

Status: Completed

Purpose: 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.
