Northern Lights Alert: See Them Tonight!
20 Jan
Summary
- Geomagnetic alert issued, increasing aurora visibility chances.
- Northern Lights visibility depends on darkness and clear skies.
- Solar wind particles interact with Earth's magnetic field to cause auroras.
A geomagnetic alert has been issued, signaling an increased potential for viewing the Northern Lights. The Met Office forecasts that the aurora may be visible overnight tonight or tomorrow morning due to an expected Coronal Mass Ejection (CME) arrival. Conditions are most favorable for observers in Scotland, Northern Ireland, and northern England. However, viewers in more southerly regions might also catch a glimpse, provided the CME arrives during darkness and skies remain clear.
The phenomenon of the Northern Lights is a result of intense solar activity. The Sun continuously emits charged particles, known as solar wind, traveling at approximately one million miles per hour. When these particles encounter Earth's magnetic field, they are guided towards the planet's magnetic poles.
Krista Hammond, Met Office Space Weather Manager, noted the uncertainty surrounding the exact timing of the CME's arrival. The potential for aurora sightings is contingent on the CME's arrival coinciding with nighttime hours and favorable weather conditions. Clear skies and darkness are crucial for experiencing this celestial display.
