A Level 3 geomagnetic storm warning has been issued as a powerful solar flare triggers stunning auroras across the US and UK, while raising concerns over GPS, radio blackouts and potential power grid disruptions.
A significant solar storm that struck Earth over the weekend is intensifying, raising alarms about potential radio blackouts and pressures on power grids. On Monday, officials issued a Level 3 geomagnetic storm warning due to the heightened solar activity. This warning indicates that disruptions could affect GPS signals, radio communications, and electrical systems. Moreover, the storm has the potential to make stunning auroras visible much further south than usual, capturing the attention of both scientists and the public alike.
This geomagnetic storm is the result of charged particles released by the Sun's outer atmosphere, known as a coronal mass ejection. The phenomenon led to the sun emitting a substantial M8.2 solar flare on Sunday—a powerful release of energy akin to an explosion. Solar flares are categorised based on their intensity, with rankings ranging from A to X, where M represents a medium strength.
Auroras are predicted to be visible across 13 states in the US, including Washington, Idaho, and portions of the Midwest and Northeast. The best viewing times are expected to fall between 10 PM and 2 AM local time. In Europe, particularly in the northern UK, the Met Office noted that auroral activity would primarily be visible in Northern Ireland and Scotland.
Experts assert that while this storm is captivating, it poses real risks. The National Oceanic and Atmospheric Administration (NOAA) has warned of possible disruptions to power systems in states such as Minnesota and Wisconsin, where the stress could lead to false alarms or system shutdowns. Dr. Tamitha Skov, an independent space weather physicist, mentioned that while the initial storm speed is significant, its strength remains moderate. "Some risk for mainly controllable power fluctuations in the power grid is possible," she noted, cautioning that this could lead to temporary disruptions in GPS signals and high-frequency radio communications.
The current solar activity has garnered heightened attention due to past experiences with severe geomagnetic storms. For instance, a G4 storm observed in April 2023 resulted in auroras observable in locations such as Alabama and northern California while also causing similar disruptions to satellite navigation and power grids. Such events have prompted officials to push for improved preparedness regarding extreme space weather. Researchers conducted a "solar storm emergency drill," simulating various scenarios of geomagnetic storms, revealing vulnerabilities in critical infrastructures. One exercise indicated a potential "internet apocalypse," with power outages extending for weeks across large parts of the U.S.
In light of these lessons, scientists and officials are advocating for a comprehensive governmental strategy to strengthen resilience against cosmic disasters. This could involve enhancing real-time data collection for space weather monitoring, deploying additional satellites for observation, and improving forecasting models to provide earlier warnings to relevant stakeholders.
While this most recent solar storm brings awe-inspiring auroras, it also serves as a stark reminder of the risks posed by solar activity. Consequently, as the spectacle unfolds, experts urge those in impacted areas to remain alert and prepared for potential disruptions.

warrant further investigation.
Freshness check
Score:
8
Notes:
The narrative references a significant solar storm that occurred over the weekend, with officials issuing a Level 3 geomagnetic storm warning on Monday. This places the event within the past week, indicating recent coverage. However, similar events, such as the severe geomagnetic storm on April 23, 2023, have been reported previously. ([noaa.gov](https://www.noaa.gov/media-advisory/severe-geomagnetic-storm-hits-earth-aurora-may-be-visible-as-far-south-as-alabama?utm_source=openai)) The presence of updated data alongside older material suggests that the article may be recycling content with recent updates, which warrants a high freshness score but should be flagged. ([swpc.noaa.gov](https://www.swpc.noaa.gov/news/update-g4-storm-observed-sunday-april-23-2023?utm_source=openai)) Additionally, the article includes a reference map with links to other sources, indicating that it may be aggregating information from multiple outlets. This practice is common in press releases and can enhance freshness by providing a comprehensive overview. However, the reliance on a single source for the core narrative raises questions about originality. The inclusion of updated data may justify a higher freshness score but should still be flagged.
Quotes check
Score:
7
Notes:
The article includes direct quotes from Dr. Tamitha Skov, an independent space weather physicist, and references to NOAA officials. A search for the earliest known usage of these quotes reveals that similar statements have been reported in previous articles covering the April 2023 geomagnetic storm. ([noaa.gov](https://www.noaa.gov/media-advisory/severe-geomagnetic-storm-hits-earth-aurora-may-be-visible-as-far-south-as-alabama?utm_source=openai)) This suggests that the quotes may have been reused from earlier reports, raising concerns about originality. However, the inclusion of updated data and the specific mention of the current event provide some level of originality.
Source reliability

Notes:
The narrative originates from the Daily Mail, a UK-based tabloid newspaper known for sensationalist reporting. This raises concerns about the reliability of the information presented. The article includes references to reputable organizations such as NOAA and mentions Dr. Tamitha Skov, an independent space weather physicist. However, the lack of direct quotes from these sources and the reliance on a single outlet for the core narrative diminish the overall reliability score.
Plausability check
Score:
8
Notes:
The article describes a significant solar storm leading to a Level 3 geomagnetic storm warning, with potential disruptions to GPS signals, radio communications, and electrical systems. It also mentions the possibility of auroras being visible much further south than usual. These claims are plausible and consistent with known effects of severe geomagnetic storms. However, the lack of supporting detail from other reputable outlets and the reliance on a single source for the core narrative raise questions about the completeness and accuracy of the information presented.
Overall assessment
Verdict (FAIL, OPEN, PASS): FAIL
Confidence (LOW, MEDIUM, HIGH): MEDIUM
Summary:
The narrative presents a plausible account of a recent solar storm and its potential impacts. However, the reliance on a single, less-reputable source, the reuse of quotes from earlier reports, and the lack of supporting detail from other reputable outlets raise significant concerns about the originality and reliability of the information presented. These factors contribute to a medium level of confidence in the overall assessment.
