Solar prominence - a large dense plasma "cloud" suspended by the magnetic field in the chromosphere and corona is one of the hallmarks of active sun. Erupting prominence may become the coronal mass ejections, the prime sources of the geomagnetic storms and space weather. Observations taken by GONG station at Learmonth, Australia on 18 August 2025 show dramatic evolution of a prominence on solar North-East limb with a rotating material forming solar tornado. Can you see a cloud funnel extending from the lower part of the prominence down to the chromosphere (thin bright layer above visible solar surface, the photosphere)? When it touches down it becomes a tornado.
