Question 1

What is a magnetic storm?

Accepted Answer

A magnetic storm is a temporary disturbance of Earth's magnetic field caused by charged particles from the Sun. It often follows a coronal mass ejection or a faster stream of solar wind.

Question 2

What is the Kp index?

Accepted Answer

The Kp index is a global measure of geomagnetic activity on a scale from 0 to 9. Values from 0 to 3 are usually calm, Kp 4 is unsettled, and Kp 5 or higher indicates a geomagnetic storm.

Question 3

What does the G1-G5 scale mean?

Accepted Answer

NOAA's G scale classifies geomagnetic storms from G1 to G5. G1 is minor, while G5 is extreme. Higher levels mean stronger potential effects on navigation, communication, power systems and sensitive people.

Question 4

Do magnetic storms depend on a city or country?

Accepted Answer

Geomagnetic activity is global. Local differences are mostly related to latitude, weather and observation conditions, not to a separate Kp value for each city.

Question 5

What is solar wind?

Accepted Answer

Solar wind is a stream of charged particles flowing from the Sun. When its speed, density or magnetic field changes sharply, geomagnetic activity near Earth can increase.

Question 6

What is IMF Bz?

Accepted Answer

Bz is the north-south component of the interplanetary magnetic field. Negative, or southward, Bz makes it easier for solar wind energy to enter Earth's magnetosphere.

Question 7

What is a coronal mass ejection?

Accepted Answer

A coronal mass ejection, or CME, is a large cloud of solar plasma and magnetic field released from the Sun. If it is directed toward Earth, it can trigger a magnetic storm.

Question 8

Can people feel magnetic storms?

Accepted Answer

Scientific evidence is mixed, but many weather-sensitive people report fatigue, headache, irritability, pressure changes or poorer sleep during active geomagnetic periods.

Question 9

What should I do on active days?

Accepted Answer

Keep a calmer pace, drink enough water, avoid unnecessary overload and follow the forecast. Magnitca is informational and does not replace medical advice.

Question 10

Who may be more sensitive?

Accepted Answer

Older people, people with cardiovascular or chronic conditions and those already sensitive to weather changes may notice active days more often. Individual reactions vary a lot.

Question 11

Can magnetic storms affect GPS?

Accepted Answer

During stronger storms, ionospheric disturbances can reduce satellite navigation accuracy. For everyday users this may be subtle, but professional systems monitor it closely.

Question 12

Can a storm damage my phone?

Accepted Answer

Everyday phones are not directly damaged by magnetic storms. Strong storms can affect some navigation and communication systems, but household electronics are generally safe.

Question 13

Why do power systems monitor space weather?

Accepted Answer

Very strong geomagnetic storms can induce currents in long conductors such as power lines. That is why the energy sector watches NOAA storm scales.

Question 14

Where does Magnitca get the data?

Accepted Answer

Space weather data comes from open NOAA Space Weather Prediction Center sources. Magnitca presents it in a clearer, more everyday-friendly format.

Question 15

How often is the data updated?

Accepted Answer

Indicators update throughout the day depending on source availability. Solar wind data is refreshed frequently, while official forecasts are updated by NOAA on their own schedule.

Question 16

Why can current Kp and today's maximum differ?

Accepted Answer

Current Kp shows the present situation, while today's maximum is the highest value measured or expected during the day. Activity can peak earlier and become calmer later.

Question 17

Can Magnitca be used for critical decisions?

Accepted Answer

For critical technical, aviation, energy or medical decisions, always check primary official sources and professional protocols. Magnitca is designed for public awareness.
