Space Weather PRO
Real-time space weather monitoring with aurora forecast map, geomagnetic indices, and solar wind data from NOAA's Space Weather Prediction Center.
Aurora Map#
A full-screen dark map displays the Aurora Ovation forecast as a heatmap overlay:
- Green zones – low aurora probability
- Yellow zones – medium aurora probability
- Red zones – high aurora probability (strong geomagnetic activity)
The map updates automatically from NOAA's Ovation model.
Kp Index#
The planetary K-index (Kp) measures global geomagnetic activity on a scale from 0 to 9:
| Kp | Status | Color |
|---|---|---|
| 0--3 | Quiet | Green |
| 3--4 | Active | Yellow-green |
| 5 | Minor Storm (G1) | Yellow |
| 6 | Moderate Storm (G2) | Orange |
| 7 | Strong Storm (G3) | Orange-red |
| 8 | Severe Storm (G4) | Red |
| 9 | Extreme Storm (G5) | Dark red |
Tap the Kp badge for a detailed description of operational impacts.
NOAA Space Weather Scales#
Three cards display the current NOAA space weather alert levels (0--5):
R – Radio Blackout#
Solar X-ray flare impact on HF radio propagation. Higher levels cause degradation or complete blackout of HF communications on the sunlit side of Earth.
- 24h forecast probabilities are shown (minor R1-R2, major R3+)
S – Solar Radiation Storm#
Energized particle impact. Elevated radiation exposure for high-altitude and high-latitude flights. At high levels, rerouting away from polar regions may be required.
- 24h forecast storm probability is shown
G – Geomagnetic Storm#
Disturbances in Earth's magnetic field. Impacts include GPS/GNSS degradation, HF radio propagation issues, and expanded aurora visibility.
Tap any card for full impact details and forecast probabilities.
Solar Wind#
Three real-time solar wind measurements from the DSCOVR satellite at L1:
- Bz (nanoTesla) – interplanetary magnetic field north-south component. Negative values (southward) increase geomagnetic storm likelihood. Color-coded: white (positive), yellow (slightly negative), orange (< -5 nT), red (< -10 nT). Tap for an info popup explaining Bz significance
- Speed (km/s) – solar wind velocity. Typical range 300--400 km/s; values above 500 km/s may drive geomagnetic activity. Tap for an info popup with speed interpretation
- Density (p/cm³) – proton density. Higher density combined with high speed and southward Bz increases storm intensity. Tap for an info popup detailing density impact
When conditions indicate a geomagnetic storm, a prominent GEOMAGNETIC STORM label is displayed.
