a temporary disturbance of the earth’s magnetic field, induced by radiation and streams of charged particles from the sun.
a sudden severe disturbance of the earth’s magnetic field, caused by emission of charged particles from the sun
See geomagnetic storm
A disturbance or fluctuation in the Earth’s outer magnetosphere, usually caused by streams of charged particles (plasma) given off by solar flares. The entry of large amounts of plasma into the upper atmosphere results in intense auroral displays and other magnetic phenomena in the polar regions of the Earth. See also aurora.
magnetic storm definition
The effect on the ionosphere of large bursts of charged particles (see electrical charge) from the sun.
Note: During a magnetic storm, radio reception can become very difficult.
- Solar time
solar time Time based on the rotation of the Earth with respect to the Sun. Solar time units are slightly longer than sidereal units due to the continuous movement of the Earth along its orbital path. For example, by the time the Earth has completed one full rotation on its axis with respect to the […]
- Solar urticaria
solar urticaria n. Urticaria resulting from exposure to sunlight.
noun 1. an emanation from the sun’s corona consisting of a flow of charged particles, mainly electrons and protons, that interacts with the magnetic field of the earth and other planetary bodies. noun 1. the constant stream of charged particles, esp protons and electrons, emitted by the sun at high velocities, its density and speed […]
