About Interplanetary Coronal Mass Ejections:
- These are massive blasts of magnetized plasma released from the Sun’s outer atmosphere, which then travel through interplanetary space.
- When those ICMEs are directed towards Earth and encounter Earth’s magnetic field, they can disturb it and cause geomagnetic storms.
- They produce colorful, dazzling auroras in Earth’s upper atmosphere.
- The level of activity of the Sun has an 11-year cycle, and more ICMEs are created during the maxima of these cycles.
- ICMEs are responsible for the most severe of geomagnetic storms when they impinge upon Earth’s magnetosphere.
- ICMEs also provide an enormous plasma laboratory to study physical processes in space.
- Impacts of Interplanetary Coronal Mass Ejections: These storms have adverse effects on satellite operations, GPS and radio communications, aviation routes, and power grids.
