![]() ![]() Number of particles registered per second, per square centimeter and per steradian. The SWPC Forecast Center is jointly operated by NOAA and the USAF.Ī unit of measurement of the strength of a magnetic field often used in space weather.Ī unit of flux intensity. National Oceanic and Atmospheric AdministrationĪmerican scientific agency. National Aeronautics and Space AdministrationĪmerican agency responsible for the civilian space program as well as aeronautics and aerospace research. It is no longer in use.Ī solar observatory located on the island of Hawaii in the United States of America. Part of Lockheed Martin which design, build, and operate solar and astrophysical observing instruments. Lockheed Martin Solar and Astrophysics Laboratory Instrument on the SOHO spacecraft used to detect and study coronal mass ejections. Large Angle and Spectrometric Coronagraph Several space weather related satellites orbit the Sun-Earth L1 point. Point in space between two celestial objects where the gravitational pull from the two objects is equal. Solar magnetic field carried by the solar wind among the planets of the Solar System. Often used to define solar wind coming from a coronal hole. Stream of solar wind at a higher than average speed. Term used to describe radio waves with a wavelength between 3 and 30 MHz. It's shape can be compared to a ballerina's skirt. ![]() #PARSEC ABBREVIATION SERIES#Series of satellites in a geostationary orbit around Earth.īoundary where the polarity of the Sun's magnetic field changes from north to south. Geostationary Operational Environmental Satellite GFZ German Research Centre for Geoscience is the national research center for Earth Sciences in Germany. Instrument package on the SDO spacecraft. Measures a broad range of energetic particles.Įuropean organization dedicated to the exploration of space.Įlectromagnetic radiation spanning from 124 nanometre down to 10 nanometre in the electromagnetic spectrum.Įxtreme Ultraviolet Variability Experiment Provides solar imagery in four different wavelengths. Values of -50nT and lower are generally considered as geomagnetic storm conditions. A negative Dst value means that Earth's magnetic field is weakened. Indicates the strength of the ring current around Earth caused by solar protons and electrons. The disappearance of a solar filament channel often due to a collapse or eruption. It is the primary source of real time solar wind and IMF data. Large cloud of solar plasma released into space due to an event on the Sun.Īn earth observation and space weather spacecraft operated by NOAA located at the Sun-Earth L1 point. Term for the compressed boundary between the fast and slow solar wind in a high speed solar wind stream from persistent coronal holes over multiple solar rotations. This enables the solar wind to escape at a high speed and cause dark holes in the corona as seen on solar images. ![]() Solar observatory located in the USA that has telescopes and instruments specifically used for studying the activities and phenomena of the Sun.Īrea on the Sun where magnetic field lines arch away from the Sun. ![]() Groups of sunspots indicated with a number. Provides continuous full-disk observations of the solar chromosphere and corona in seven extreme ultraviolet channels. Was the primary source of real time space weather data until DSCOVR took over in 2016. Solar and space exploration spacecraft located at the Sun-Earth L1 point. ![]()
