Space Weather Today
Live solar and geomagnetic conditions, explained with evidence-first context.
Will I see the aurora? — estimate for your latitude
Enter your magnetic latitude (approx. your town's latitude works well). During a storm the auroral oval shifts toward the equator — higher Kp means better chances at lower latitudes.
Rule-of-thumb estimate only — actual visibility depends on Bz direction, local weather, and darkness. Not a forecast guarantee.

Aurora Ovation Map
Live aurora forecast from NOAA SWPC (OVATION model). Bright green = higher probability of visible aurora. Heavier geomagnetic activity (higher Kp) pushes the oval to lower latitudes.

The Sun Now — GOES SUVI
Live extreme-ultraviolet views of the Sun from NOAA's GOES SUVI instrument. Longer wavelengths (131, 195, 284 Å) reveal active regions and coronal loops — where flares erupt.
Images © NOAA SWPC · GOES-19 SUVI · updated ~every 4 minutes. The bright 131/94 Å regions are where flares are most likely.
Aurora Forecast Outlook
Estimated Kp over time (NOAA SWPC). Higher Kp = better aurora chances at lower latitudes. Official 3-day Kp forecast sources.
Weekly narrative forecast from NOAA SWPC (WWV). Operational forecast shown for context — not a health indicator.
NOAA Space Weather Scales — how strong is it?
Match today's conditions against the official NOAA storm scales. R = radio blackouts, S = solar radiation storms, G = geomagnetic storms.
R · Radio Blackout
R1 (M1) → minor HF. R2 (M5) → degraded. R3 (X1) → wide blackouts. R4 (X10), R5 (X20) → extreme.
S · Radiation Storm
S1 (10 MeV ≥10 pfu) → minor. S3 → radiation levels affecting aircraft. S5 → extreme, risk to crew & astronauts.
G · Geomagnetic Storm
G1 (Kp 5) → power-grid fluctuations. G3 (Kp 7) → high latitude impacts. G5 (Kp 9) → extreme, worldwide.

3-Day Geomagnetic (Kp) Forecast
Estimated planetary K-index for the next 3 days (3-hour steps) from NOAA SWPC. Kp ≥ 5 (G1) marks the threshold where aurora becomes visible at mid-latitudes.

How to Read This Dashboard
⚡ These are measurements
All values are direct or near-real-time measurements of solar and near-Earth space conditions from NOAA SWPC and NASA DONKI instruments.
🛰 Established relevance is technical
Space weather primarily affects technological systems: satellite operations, GNSS/GPS accuracy, HF radio communication, power grids, spacecraft electronics, and aviation radiation at high altitudes/polar routes. Aurora visibility increases with geomagnetic activity.
🧬 Health evidence is limited
Current scientific evidence does not support using these metrics for personal health, mood, productivity, or behavior predictions. GrivavaLAB has published null-result analyses and robustness tests confirming no credible population-level associations with several health indicators.
📐 Status rules are documented
Overall status (Quiet/Unsettled/Active/Storm) follows deterministic Kp thresholds documented in our methodology. No proprietary or black-box scoring is used.
