Vietnamese tourists hunt for rare red aurora borealis amidst the strongest solar storm in 20 years.

Vietnamese tourists have had unforgettable memories witnessing firsthand the dazzling night sky in Europe with the rare phenomenon of the red aurora borealis.

A rare red aurora borealis was seen in the European sky recently on the night of January 19th (local time). This phenomenon occurred as an unusually strong solar radiation storm was heading towards Earth these days, creating a stunning spectacle in the Northern Hemisphere sky. Photo: Quy Thieu

This phenomenon is less common than the green aurora and occurs during powerful solar storms. The night sky is painted with brilliant shades of deep red, purple, pink, and more. Photo: Quy Thieu

The red aurora forms when oxygen atoms at very high altitudes (over 200 km) are excited by energetic particles from the solar wind. At this altitude, the air is very thin, so the energy is released slowly, resulting in red light instead of the more common green light. Photo: Quy Thieu

The aurora borealis, with its vibrant red and blue hues, blazed across the sky over Berlin, Germany. This was due to the influence of the strongest S4 solar radiation storm in over 20 years, currently heading towards Earth. The unusually bright red aurora was observed in the US, UK, and as far as northern Italy in Europe; even in China. Photo: Quy Thieu

The best time to observe the aurora borealis is usually around midnight. For a clearer view, people should avoid areas with a lot of artificial light, find a dark space, and allow time for their eyes to gradually adjust to the darkness. Photo: Kevin Phan
