I. What is the Magnetosphere? The magnetosphere is a region surrounding Earth that is influenced by the planet’s magnetic field. It extends from the Earth’s surface out into space, forming a protective shield that helps to deflect harmful solar radiation and charged particles. The magnetosphere plays a crucial role in protecting our planet from the … Read more
I. What is ACE (Advanced Composition Explorer)? The Advanced Composition Explorer (ACE) is a spacecraft launched by NASA in 1997 with the primary goal of studying space weather. ACE is equipped with a suite of instruments that allow it to monitor and collect data on particles and magnetic fields in the solar wind, as well … Read more
I. What is the Space Weather Prediction Center (SWPC)? The Space Weather Prediction Center (SWPC) is a division of the National Oceanic and Atmospheric Administration (NOAA) that is responsible for monitoring and forecasting space weather events. Space weather refers to the environmental conditions in space as influenced by the sun and the solar wind. The … Read more
I. What are Geomagnetically Induced Currents (GICs)? Geomagnetically Induced Currents (GICs) are electric currents that are induced in power systems and pipelines due to geomagnetic storms. These storms are caused by disturbances in the Earth’s magnetic field, usually triggered by solar activity such as solar flares or coronal mass ejections. When these disturbances interact with … Read more
I. What is the K-index? The K-index is a measurement used to quantify the overall geomagnetic activity on Earth. It is a scale that ranges from 0 to 9, with 0 indicating very quiet geomagnetic conditions and 9 indicating extremely disturbed conditions. The K-index is an important tool for monitoring and predicting space weather events … Read more
