Forecasted Magnetic Storms on August 7-8: Expert Opinions Revealed
A moderate geomagnetic storm is set to hit Earth on August 8, 2022, primarily due to a glancing blow from a coronal mass ejection (CME). Here's what you need to know about this event and its potential effects.
The storm is the result of the interaction between solar eruptions and Earth's magnetic field, a phenomenon known as geomagnetic storms. NASA's forecast predicts the storm's level to be around 5 points, which is considered moderate.
Satellite data is regularly updated, allowing for real-time tracking of changes in solar activity. This data is monitored using NOAA satellites, TESIS, and international laboratories.
The anticipated storm could have several potential effects:
- Satellites: The storm could cause minor disruptions or damage to satellites by disturbing the near-Earth space environment, possibly impacting satellite electronics and onboard systems due to increased charged particles and electromagnetic interference. However, for the August 8 event, the impact was expected to be moderate, so significant satellite failures were not highly likely but monitoring and precautions would be prudent.
- Radio and Navigation Systems: The storm might induce radio blackouts or signal degradation, especially in high-frequency (HF) radio communications used by aviation and maritime sectors. GPS and other navigation systems can be affected by changes in the Earth's ionosphere caused by geomagnetic activity, leading to decreased accuracy or intermittent signal loss during the storm period.
- Power Grids: Moderate geomagnetic storms can induce geomagnetically induced currents (GICs) in power grids, potentially stressing transformers and causing voltage instability or temporary outages, particularly at high latitudes. Although the August 8 storm was moderate, it poses a risk to sensitive grid infrastructure and requires preventive measures by grid operators to minimize impact.
- People with Chronic Heart and Vascular Diseases: Geomagnetic storms have been linked in some studies to disturbances in human cardiovascular health, including increased risks of heart arrhythmias or vascular stress, although the exact mechanisms remain unclear and effects vary among individuals. People with pre-existing heart and vascular conditions might be more susceptible to physiological stress during geomagnetic storms.
In summary, the moderate geomagnetic storm of August 8, 2022, is expected to create auroras visible in northern and some mid-latitudes, cause minor to moderate disturbances to satellites, radio, navigation systems, and possibly stress power grids, while potentially impacting sensitive individuals with heart and vascular conditions to a lesser, less well-quantified extent.
Relative calm is expected in the coming days, but experts warn of the possibility of sudden changes and intensification of magnetic disturbances. The solar flare recorded on August 5 could lead to a geomagnetic storm around August 8.
For businesses and utility services, it is important to prepare energy and communication systems for possible disruptions during magnetic storms. People with cardiovascular diseases should consult a doctor and take preventive measures during magnetic storms. Regular checks and backup power sources can help minimize risks and ensure uninterrupted operation during magnetic storms.
During magnetic storms, it is recommended to pay special attention to health, avoid stress and physical exertion, particularly for those with chronic heart and vascular diseases. Stay attentive and monitor updates, as small flares can lead to the intensification of magnetic storms.

- The moderate geomagnetic storm, predicted on August 8, 2022, could affect not only the scientific field, such as satellite data and space and astronomy research, but also the health-and-wellness sector, as it may potentially induce health issues in people with pre-existing heart and vascular conditions.
- In addition to its impact on the space-and-astronomy realm, this anticipated storm may create challenges for various technologies, including satellite operations, radio and navigation systems, and power grids, underscoring the importance of proper preparedness for businesses and utility services in mitigating potential disruptions.
