A massive coronal hole stretching over 800,000 kilometres has been detected on the Sun's surface, releasing high-speed solar wind toward Earth. This phenomenon is expected to intensify auroral activity on January 31 and February 1. The solar wind, travelling at speeds exceeding 500 kilometres per second, could lead to minor geomagnetic storm conditions. These disturbances may result in vibrant northern and southern lights in higher latitudes, enhancing visibility for aurora enthusiasts.

As solar wind collides with Earth's magnetic field, it energises oxygen and nitrogen atoms in the upper atmosphere, resulting in the dazzling auroras observed near the poles. Experts suggest that although G1 storms are not rare, their effects on auroral activity can vary. Space weather remains difficult to predict, meaning the intensity of displays is uncertain.
