The National Oceanic and Atmospheric Administration issued a severe geomagnetic storm watch, expected to bring the delights of seeing the Northern Lights but also potentially pose problems for power grids. The storm was caused by several earth-directed coronal mass ejections and strong flares associated with a large sunspot cluster. While most geomagnetic storms cause little disruption, extreme cases can lead to significant power outages, satellite issues, and disruptions in communications. NOAA has notified operators of systems that could be affected so they can take protective action.
Consumer wireless networks are unlikely to be affected by geomagnetic storms, so your phone is not likely to experience disruptions. However, high-frequency radio users in the aurora viewing zone may face some interruptions. Severe geomagnetic storms could impact the power grid, but wireless carriers have backups and can deploy mobile cellular towers if needed. Despite potential disruptions, most people will not be affected or need to take special precautions beyond usual storm preparation.
Geomagnetic storms also offer unique opportunities to see auroras in the night sky. The storms create plasma that results in stunning aurora displays, especially during intense storm phases. Auroras may be visible as far south as Alabama and Northern California during severe storms. Viewing opportunities can be challenged by light pollution in urban areas and unpredictable weather conditions, making sightings of auroras rare in some locations. Traveling to Alaska or northern countries such as Finland and Scandinavia is recommended for those hoping to witness and photograph auroras.
Aurora sightings can be compared to a popular outdoor hobby like fishing, requiring patience and the perfect conditions for a successful experience. City dwellers face challenges due to light pollution inhibiting visibility of stars and planets. Driving to rural areas away from city lights and monitoring weather conditions can increase chances of seeing auroras. There are trip planners organizing tours to locations known for aurora sightings, providing opportunities for enthusiasts to experience the natural phenomenon. By taking precautions and being prepared, skygazers can enjoy the beauty of auroras during geomagnetic storms.
