In recent times, there has been a keen interest in understanding Sun-Earth connection events, such as solar flares, CMEs and concomitant geomagnetic storms, which are large scale disturbances in the magnetic field of the Earth’s lasting only for a few days. Magnetic storms are the most dramatic and perhaps important component of space weather effects on Earth. During intense magnetic storms, the auroral activity becomes intense and the auroras could be seen at the sub-auroral to mid-latitude stations.
Modern society is becoming ever increasingly dependent on technology that is affected in some ways by conditions in the near-Earth space environment. Super-intense magnetic storms, although relatively rare, have the largest societal and technological relevance. Such storms can cause life-threatening power outages, satellite damage, communication failures and navigational problems. This talk will focus on the geomagnetic storm of 1-2 September 1859, the most intense storm in the recorded history. By applying the knowledge of interplanetary and solar causes of magnetic storms gained from the spaceage observations, the interplanetary cause of this super-intense geomagnetic storm will be deduced. This talk will discuss various aspects of magnetic storm and space weather research that can impact the society.
