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.
Magnetic phenomenon that causes auroras on Earth has now surprisingly been discovered creating giant magnetic bubbles around Venus, a planet without a magnetic field. The Northern and Southern Lights on Earth are caused by magnetic lines of force breaking and connecting with each other. This process, known as magnetic reconnection, can explosively convert magnetic energy to heat and kinetic energy.
A series of powerful flares and ejections of plasma in the Sun, which led to very strong over the past five years magnetic storm on Earth, could be the beginning of the general level of solar activity, which may last until the end of 2011.
