The stream of the solar wind is approaching the Earth. Estimated time of arrival is June 18-19. The gaseous material flows from the hole in the Sun’s atmosphere, shown here in the ultraviolet image of NASA’s Solar Dynamics Observatory.
Coronal holes are dark, because the hot glowing gas previously contained in them is absent – in this case, approaching our planet.
According to NOAA forecast, the probability of occurrence of geomagnetic activity on June 19 is 25%, since the solar wind will affect the Earth’s magnetic field. This will be an insignificant space weather event. However, it can lead to the appearance of auroras, which are best observed in the southern hemisphere.
