Geomagnetic Storm Triggers Aurora Display Across Northern US on March 23

A G3-class geomagnetic storm impacted Earth on Sunday, March 23, creating conditions for auroras in the northern United States. The NOAA reported the storm, linked to a coronal mass ejection (CME) from the Sun, reached Kp 7 intensity. Visibility extended as far south as Nebraska and Indiana. The CME, originating from a M1-class solar flare on March 21 in solar region 4028, was directed toward Earth. The Russell-McPherron effect, aligning magnetic fields during the equinox, amplified the storm's impact. NOAA forecasts additional minor (G1) and moderate (G2) geomagnetic storms on March 24 and 25, respectively. While significant, this storm was less intense than the G5 event on May 10, 2024. NOAA advises consulting their 30-minute forecast for real-time updates. The event occurs during the solar maximum, increasing the frequency of solar flares and geomagnetic storms.
