Moderate Solar Activity Predicted For Today, August 28
A warning has been issued regarding the potential impact of G4 solar storm. This information is directed at government agencies and critical infrastructure operators. They can implement measures to reduce potential damage to vital infrastructure and essential services. This is prepared by SSP.
The G-scale measures global geomagnetic activity, tracking fluctuations in Earth's magnetic field. It ranges from G1 (minor) to G5 (extreme) levels.
G4-level geomagnetic storms can notably disrupt:
- Critical infrastructure, such as power grids, leading to power outages.
- Satellite services, which can hinder communication and impact global positioning, navigation, and timing services, especially those relying on high-frequency radio communication.
If G4 geomagnetic conditions arise, observers may see bright auroras at unusually low latitudes. This includes dark-sky regions near Sydney and Perth.
