A significant alert regarding solar activity indicates that people in the UK are in for a stunning exhibition of the Northern Lights tonight.
The magnificent display is occurring as the remnants of a massive Coronal Mass Ejection (CME) that erupted from the Sun on Monday are finally reaching Earth, promising a spectacular light show.
Current space weather conditions are ideal for a show this weekend, with heightened solar activity expected to make the beautiful lights visible across various regions of the UK.
In an alert shared this afternoon, the AuroraWatch UK account on X warned, “Red alert: aurora likely.”
The breathtaking phenomenon is unfolding as solar particles from a Coronal Mass Ejection (CME) that discharged from the Sun on Monday are reaching Earth. A CME is a large plasma cloud released into space, typically accompanying a Solar Flare, which is a burst of light and radiation.
When the disturbance from the CME reaches Earth, interactions with the planet’s magnetic field trigger the iconic lights in the upper atmosphere.
According to the Met Office’s Space Weather Forecast, solar activity may continue to be high, potentially enabling the aurora to be widely visible again tonight.
The forecast stated, “Solar winds will initially be slightly elevated to elevated following the arrival of the second anticipated CME. Several more CME arrivals are predicted to possibly reach Earth through March 21, likely intensifying solar winds to become elevated to strong intermittently. Additionally, a fast wind from a coronal hole is expected starting from March 21, which could sustain elevated to strong solar winds throughout the period.”
The spring equinox period increases the likelihood of witnessing the northern lights as Earth’s alignment with the Sun exposes it more to solar wind activity during this time.
For the best chance of observing the aurora, it is recommended to choose a clear night, locate a dark area free of light pollution, and face north.
