A geomagnetic storm reached G2 level on July 3, 2026, according to the National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center (SWPC).
Current Conditions
Prior to the storm, the Kp index was measured at 1.33 on July 2, 2026, with no geomagnetic storm activity observed. The Kp index, ranging from 0 to 9, indicates the severity of geomagnetic activity. Higher values suggest increased aurora visibility at lower latitudes.
Forecast Details
The storm peaked on July 3, 2026, with a Kp index of 6.0, corresponding to a G2 geomagnetic storm level. This level could potentially make auroras visible as far south as the northern United States and similar latitudes. The storm subsided by July 4, 2026, with the Kp index dropping to 4.67 and no significant storm activity forecast.
Aurora Visibility
The G2 storm level indicates that auroras may be visible at lower latitudes than usual. A Kp index of 6.0 can make auroras visible as far south as the northern tier of the United States, including states like Michigan, Minnesota, and New York, under clear, dark sky conditions. However, visibility depends on local conditions, light pollution, and the season. Near the summer solstice, long twilight periods may make auroras harder to see even during a strong storm.
