See the Northern Lights Monday Across the U.S

Highlights
  • A major solar flare from the AR3825 sunspot occurred on September 14, leading to a forecast of a G3-class geomagnetic storm.
  • The auroras, typically seen in polar regions, may be visible as far south as California, Missouri, and Colorado due to extreme geomagnetic conditions.
  • Observers should seek dark skies away from urban light pollution for the best chance to see the Northern Lights.
Story

On September 14, a significant X4.5 class solar flare erupted from the AR3825 sunspot, leading to predictions of a strong G3-class geomagnetic storm. This solar activity is part of a period of heightened solar events, with the current solar cycle reaching a 23-year peak. NOAA forecasts indicate that the geomagnetic storm conditions may persist through September 17, although the intensity could vary between G2 and G4 levels. The interaction of charged particles from the sun with Earth's magnetic field creates the auroras, typically visible in polar regions but potentially observable much further south during extreme conditions. For those hoping to witness the Northern Lights, the best viewing opportunities will be in areas with minimal light pollution and a dark northern horizon. The presence of a waxing gibbous moon may hinder visibility, making it essential for observers to find optimal locations. The auroras are formed when solar particles collide with Earth's magnetic field, resulting in colorful displays of green and red light. These phenomena can be seen at latitudes as low as 40 degrees north and south during intense geomagnetic storms. As the equinox aurora season begins, enthusiasts are encouraged to prepare for potential sightings. The unpredictability of space weather means that conditions can change rapidly, so staying informed through reliable forecasts is crucial. Observers should also consider using light pollution maps to identify the best spots for viewing. In summary, the upcoming days present a unique opportunity for many across the U.S. to experience the Northern Lights, thanks to recent solar activity. With the right conditions and locations, these stunning displays could be visible to a broader audience than usual.
