Executive Summary
- Geomagnetic storms are increasing the visibility of the Northern Lights in several northern U.S. states.
- The National Oceanic and Atmospheric Administration (NOAA) provides forecasts indicating the potential viewing areas and the intensity of the aurora based on the Kp index.
- The best viewing conditions involve finding a north-facing vantage point away from light pollution between 10 p.m. and 2 a.m. local time; solar activity peak will likely persist into 2026.
Event Overview
Geomagnetic storms are anticipated to enhance the visibility of the Aurora Borealis, also known as the Northern Lights, across several northern states in the U.S.. NOAA forecasts, based on the Kp index, predict varying levels of auroral activity. The aurora borealis is caused by interactions between electrons from solar events, such as geomagnetic storms and solar flares, and the Earth's atmosphere. The recent increase in solar activity, expected to continue into early 2026, provides more frequent opportunities to witness this natural phenomenon.

|---|---|---|---|
| Forbes (May 5, 2025) | Northern Lights visibility forecast for Sunday night into Monday morning. | Forecast specified a Kp index of four and indicated minor geomagnetic storms; visibility in Alaska, North Dakota, most of Montana, Minnesota and Wisconsin, and parts of Washington, Idaho, South Dakota, Michigan and Maine. | Informative |
| Forbes (May 6, 2025) | Northern Lights visibility forecast for Tuesday night. | Forecast specified a Kp index of four; Earth’s magnetic field expected to reach minor storm levels Tuesday and persist through Wednesday; visibility in parts of northern Canada and Alaska, with a view line marking a minimal opportunity forecast just north of Iowa. Areas of northeastern Washington, northern Idaho, Montana, North Dakota, northern South Dakota, Minnesota, northern Wisconsin, Upper Michigan and northern Maine will have a lower chance. | Informative |
| Forbes (May 5, 2025) | Northern Lights visibility forecast for Monday night after geomagnetic storms. | Forecast specified a Kp index of three, potentially increasing to four; minor to moderate radio blackouts are also expected through Wednesday; visibility in northeastern Washington, northern Idaho, northern Montana, North Dakota, northern Minnesota, Upper Michigan and northern Wisconsin. | Informative |
Key Details & Data Points
- What: Increased chance of viewing the Northern Lights due to geomagnetic activity. The visibility and intensity depend on the Kp index and geomagnetic storm levels.
- Who: The National Oceanic and Atmospheric Administration (NOAA) is providing forecasts. Residents of northern U.S. states are potential viewers.
- When: Forecasts were made for May 5th, May 6th, and May 7th of 2025. The best viewing time is between 10 p.m. and 2 a.m. local time.
- Where: Visibility varies by date but includes Alaska, North Dakota, Montana, Minnesota, Wisconsin, Washington, Idaho, South Dakota, Michigan, and Maine.
Key Statistics:
- Key statistic 1: Kp index of 4 (on a scale of 9) (forecast for May 4th and May 6th, indicating brighter aurora)
- Key statistic 2: Kp index of 3 (on a scale of 9) (forecast for May 5th, indicating lower aurora visibility)
- Key statistic 3: Solar maximum achieved in October 2024 (suggesting increased visibility through early 2026)
Analysis & Context
The reports consistently point to geomagnetic activity influencing the visibility of the Northern Lights. The Kp index, a measure of geomagnetic activity, is a key indicator used by NOAA to forecast the aurora's visibility. A higher Kp index generally means a greater chance of seeing the Northern Lights further south. All reports highlight the importance of finding a dark location away from city lights for optimal viewing. The extended period of increased solar activity suggests that opportunities to view the aurora will continue into 2026.
Conclusion
Geomagnetic storms are increasing the probability of witnessing the Northern Lights in several northern U.S. states. NOAA's forecasts provide valuable insights for potential viewers, guiding them to the best times and locations for observation. With the solar maximum expected to last into 2026, opportunities to view the aurora borealis will remain plentiful, encouraging enthusiasts to monitor forecasts and seek out optimal viewing conditions.
