ELF Atlas

Explore the Sun’s influence on Earth with ELF Atlas, an accessible space weather app powered by NOAA and NASA data. Study solar activity, track auroras and geomagnetic storms, or compare well-being claims with underlying observations.

SPACE WEATHER AT A GLANCE

See major indicators, current and recent values, observation times, status, and data availability in one atlas.

PLANETARY KP INDEX

Track the estimated Kp index and geomagnetic conditions from quiet and unsettled to active and storm levels.

SOLAR WIND

Monitor spacecraft measurements of solar wind speed, proton density, temperature, recent trends, and conditions approaching Earth.

INTERPLANETARY MAGNETIC FIELD

Track Bt, Bx, By, and Bz, including southward Bz associated with stronger geomagnetic activity.

SOLAR X-RAY ACTIVITY

Track GOES X-ray irradiance, compare wavelength channels and flux history, and view A, B, C, M, and X flare classes.

AURORA MODEL

Explore NOAA OVATION outputs for both hemispheres, compare polar regions, and check observation and forecast times.

LATEST SOLAR IMAGE

View, enlarge, and zoom into the latest NASA Solar Dynamics Observatory imagery to examine active regions, coronal holes, and other structures.

SPACE WEATHER ALERTS

Read and filter NOAA alerts, watches, warnings, summaries, corrections, and cancellations, with issue times, product identifiers, and message codes.

SCIENCE WITHOUT THE HYPE

Solar flares, geomagnetic storms, solar energy, space weather symptoms, consciousness shifts, Schumann resonance, and planetary energy are often linked online. ELF Atlas shows measured, estimated, modeled, and imaged data about the Sun and near-Earth environment.

It does not claim space weather predicts moods, symptoms, consciousness, earthquakes, disasters, or personal events. Use transparent data to assess ideas, compare claims, and form an informed view.

WHY USE ELF ATLAS?

Access multiple indicators and recent trends in one approachable interface. Distinguish observations, estimates, and models; see UTC timestamps and active spacecraft; open original NOAA and NASA sources; choose light or dark themes; access 77+ languages; and enjoy an ad-free experience with a subscription.

Designed for education, general information, scientific curiosity, aurora enthusiasts, space weather observers, and anyone seeking reliable solar and geomagnetic data.

ELF Atlas is not a medical device, diagnostic service, forecasting authority, or emergency warning system. Never substitute it for professional medical advice or official safety information.

Explore the data. Question the claims. Understand Earth’s space environment.
