Magnetic storms are phenomena caused by solar activity that can significantly affect both technology and human health. At the end of June 2025, a new powerful geomagnetic storm is expected, potentially lasting from a few hours to several days. This event is drawing attention from scientists and the general public alike.
As noted by the editorial team at the Baltimore Chronicle, special attention should be paid to individuals with cardiovascular diseases and weather sensitivity.
What Is a Magnetic Storm and Why Does It Occur?
A magnetic storm is a disturbance in the Earth’s magnetic field caused by solar flares and coronal mass ejections. These storms are classified by the Kp index, with Kp = 5–9 indicating storms of varying intensity.
How a Magnetic Storm Forms:
- A solar plasma ejection reaches Earth within 1–3 days
- It interacts with the magnetosphere, disrupting the magnetic field
- Geomagnetic waves can last from several hours to several days
These changes affect power grids, GPS signals, and can worsen people’s well-being. Storms are categorized as weak, moderate, or strong.
Magnetic Storm Forecast for June 30, 2025
According to astronomical observations, a geomagnetic storm of G2–G3 level is expected on June 30. This is a moderate to above-average level that may cause noticeable discomfort in people.
Key Forecast Details:
- Kp Index: 6–7
- Duration: up to 36 hours
- Likely peak time: from 10:00 AM to 6:00 PM Kyiv time
- Risk of communication disruptions: high, especially in northern regions
Scientists recommend staying updated via the U.S. Space Weather Prediction Center (SWPC) or the Ukrainian Hydrometeorological Center.
How a Magnetic Storm Affects Human Health
Geomagnetic storms primarily affect weather-sensitive individuals. Fatigue, headaches, blood pressure issues—these are typical symptoms during a storm. People with chronic conditions are especially vulnerable.
Most Common Complaints During a Storm:
- Sleep disturbances
- High blood pressure
- Arrhythmia
- Anxiety and irritability
- General fatigue
Older adults, pregnant women, and people with cardiovascular diseases should be particularly cautious.
How to Prepare for a Magnetic Storm
Although it’s impossible to fully shield yourself from a magnetic storm’s effects, there are ways to minimize its impact.
Tips for Weather-Sensitive People:
- Stay well-hydrated
- Avoid stress and heavy physical exertion
- Limit caffeine and alcohol intake
- Get enough sleep (7–8 hours minimum)
- Take calming medication if necessary (only as prescribed)
General Recommendations:
- Check the condition of electrical appliances
- Prepare backup power sources
- Limit GPS and Wi-Fi usage if disruptions occur
- Follow news updates regularly
Impact on Technology and Transportation
During a magnetic storm, satellite systems, mobile networks, and power grids may experience failures.
Potential Consequences:
- GPS navigation glitches
- Temporary radio communication blackouts
- Damage to transformers
- Voltage fluctuations in electrical systems
Airlines and telecommunications providers are at the greatest risk.
Which Regions in Ukraine Are More Vulnerable?
Northern regions—Zhytomyr, Chernihiv, and Kyiv oblasts—are more frequently affected by strong geomagnetic waves. Southern regions like Odesa and Kherson experience milder effects.
Comparative Impact Table:
| Region | Impact Level | Recommendations |
|---|---|---|
| Kyiv Region | High | Minimize physical activity |
| Lviv Region | Medium | Monitor blood pressure |
| Kharkiv Region | High | Prepare necessary medications |
| Odesa Region | Low | Maintain regular routine |
Are Magnetic Storms Dangerous for Children?
Children are generally less sensitive to geomagnetic changes, but some may show signs of fatigue or increased excitability.
Advice for Parents:
- Maintain regular sleep schedules
- Avoid excessive extracurricular overload
- Spend more time outdoors
- Limit screen time
Pay special attention to children with diagnosed neurological conditions.
Scientific Perspectives on Geomagnetic Storm Effects
Research shows that strong magnetic storms can affect human biorhythms, though only indirect links have been statistically confirmed.
Scientists’ Opinions:
- NASA: reports increased health complaints during storms
- Ukrainian researchers: statistically significant connection between storms and well-being
- European universities: have not yet recognized storms as clinical factors
However, all researchers agree that it’s best to avoid stress and stay calm during a storm.
What to Expect on June 30
The magnetic storm on June 30, 2025, is expected to be one of the most noticeable in the first half of summer. It will likely affect the health of sensitive individuals, disrupt technology and communications. Timely preparation and attention to your condition will help you get through it smoothly.
