This week, the flow of the solar wind reached the Earth’s magnetic field and caused a long lasting geomagnetic storm. Despite the absence of active zones on the Sun (spots) of geomagnetic disturbances in the Earth’s atmosphere were caused by the flow of the solar wind emerging from coronal holes in the solar atmosphere.
These are the holes in the body, can be formed even when the active areas are completely absent. Today in the Sun watching a giant coronal hole. A new stream of solar wind will reach Earth from the 11th and 12th of June, which cause geomagnetic storms.
