Since coronal holes are areas in which the magnetic field is open, and the solar wind can easily lapse into outer space, then the world could begin magnetic storms. According to calculations by NASA geophysicist, it will happen on June 29-30. The impact will affect, first of all, the poles where the aurora should be expected.
