Lviv is a city with a rich history and a unique atmosphere. But even here, geomagnetic activity can affect well-being. Our forecast will help Lviv residents prepare for magnetic storms using accurate NOAA data. Take care of your health and plan your day with the Kp-index in mind.
📊 Kp-index interpretation
The Kp-index is measured from 0 to 9 and shows the level of geomagnetic activity. The higher the value, the stronger the impact on health and technology.
| Kp | Level | Health impact | Technology impact |
|---|---|---|---|
| 0–3 | 🟢 Quiet | Safe, well-being normal | Technology works stably |
| 4 | 🟡 Active | Mild headaches in weather-sensitive people | Minor GPS glitches possible |
| 5 | 🟠 Weak storm | Headaches, fatigue, blood pressure changes | Radio and navigation disruptions |
| 6 | 🟠 Moderate storm | Severe headaches, insomnia | Power grid and satellite issues |
| 7–9 | 🔴 Strong/extreme | Serious health problems, risk of heart attacks | Massive electronics and communications failures |

❓ Frequently Asked Questions
What is a magnetic storm in simple words?
A magnetic storm is a disturbance of the Earth's magnetic field caused by solar flares. When the Sun ejects streams of charged particles, they reach our planet and interact with the magnetosphere, creating magnetic disturbances.
