The sun constantly emits streams of particles from its atmosphere out into the solar system. This emission is referred to as the solar wind. Sometimes there are solar storms or solar flares, resulting in heavier emissions than normal. If the Earth passes through one of these emissions, then the resulting auroras will be brighter than usual. If the ...
The Earth has a magnetic field surrounding it because of the iron-nickel core at the center of our planet. Understanding this magnet field is essential to understanding the science behind the aurora borealis. The magnetic field exiting from the core is responsible for the magnetic north and south poles we use when we navigate with a compass. It als...
The movement of charged particles in Earth’s magnetic field produces powerful electric currents. In 1859, an aurora and the associated electrical storm were so powerful that people read newspapers at night by its light. Telegraph operations were disrupted as the current produced by the charged particles overwhelmed the normal currents used in the l...
Apps providing forecasts of probable auroras rely on scientific measurement and calculation of changes in the strength of Earth’s magnetic field. Single measurements are tracked as a K-index. An aggregation of the measurement stations is used to produce a Planetary K-index (Kp). The higher the Kp value, the more likely an aurora will appear and the...
