On Earth began the magnetic storm. The index of geomagnetic indignations of Kp in the

morning on Saturday reached value 5. 5 is a minimum level which is considered the magnetic storm, and then the index rose to 6. The reason of geomagnetic indignations can be the stream of a high-speed solar wind. The stream is the loaded particles which source is the coronal hole on the Sun (rather dark area on a solar disk with open lines of a magnetic field). This hole was noticed in pictures from the “Stereo” probe on the invisible part of the Sun 10 days ago. Then scientists predicted that on June 28-29 when it comes to our part, the magnetic storm of moderate force can begin.
