== Summary ==

'''Space weather''' is the collective term for time-variable phenomena in the near-Earth space environment driven by the Sun, including solar wind, coronal mass ejections (CMEs), solar energetic particle events, and their downstream effects on the [[Geomagnetic_Field|geomagnetic field]], [[Earth-Ionosphere_Cavity|ionosphere]], and ground-level EM environment. Space-weather forecasting and characterisation are operational concerns of NOAA, ESA, and other national space-weather services.

== Drivers ==

* '''Solar wind''': continuous outflow of plasma (~ 400 km/s, varying with solar conditions) from the Sun.
* '''Coronal mass ejections (CMEs)''': massive plasma / magnetic-field eruptions, typically requiring 1-4 days to reach Earth, capable of producing major geomagnetic storms.
* '''Solar flares''': rapid electromagnetic emission events, reaching Earth in 8 minutes and immediately affecting the dayside ionosphere.
* '''Solar energetic particles''' (SEPs): high-energy protons / heavy ions accelerated by flares and CME shocks, reaching Earth in minutes to hours, affecting satellites and polar ionosphere.
* '''Coronal hole high-speed streams''': lower-density, high-velocity (~ 600-800 km/s) wind from coronal magnetic-field "open" regions; produce recurring geomagnetic storms.

== Effects ==

* '''Geomagnetic storms''' (measured by [[Geomagnetic_Indices_Kp_Dst|Kp and Dst]]): depression of the surface geomagnetic field, ring-current intensification.
* '''Ionospheric storms''': ionisation enhancement / depletion, disruption of HF radio propagation.
* '''Auroras''': enhanced and equatorward-displaced during major storms.
* '''Satellite anomalies''': single-event upsets, solar-panel degradation, increased atmospheric drag on LEO satellites.
* '''Power-grid risk''': geomagnetically-induced currents (GICs) in long transmission lines; the 1989 Quebec storm caused a 9-hour outage.
* '''Communications and navigation''': HF radio outages, GPS positioning errors during storms.

== Major Historical Events ==

* '''1859 Carrington event''': the largest known geomagnetic storm in the instrumental era, observed by Richard Carrington. Telegraph systems failed worldwide; auroras seen near the equator. Modern equivalent estimated at $1-2 trillion in economic damage.
* '''1989 Quebec storm''' (Dst ≈ -589 nT): collapsed the Hydro-Québec grid; 6 million people without power for 9 hours.
* '''2003 Halloween storms''' (Dst ≈ -422 nT): widespread satellite anomalies; auroras visible to mid-latitudes.

== Operational Monitoring ==

The principal monitoring infrastructure:

* '''SOHO, ACE, DSCOVR''' spacecraft at the L1 Lagrange point — provide ~ 30-60 minute solar-wind warning.
* '''GOES, SDO''' geostationary satellites — solar X-ray and EUV monitoring.
* '''Worldwide magnetometer network''' — Kp / Dst calculation.
* '''Ionospheric sounding networks''' — real-time ionosphere state.

NOAA's Space Weather Prediction Center (swpc.noaa.gov) is the principal US operational source.

== Psionic Relevance ==

In the [[Psionics|psionic framework]], space-weather variables are the principal '''external modulators''' of the Earth's EM environment. The framework predicts measurable correlations between space-weather indices and ψ-field-mediated biological / consciousness phenomena. The empirical literature (Persinger et al., GCP, multiple epidemiological studies) supports this prediction at small effect sizes.
