The sun hit mercury
The magnetic field near the Western edge of the disk of the Sun was personnalise and exploded, sending a coronal mass ejection into space towards mercury.

According to estimates of the National administration on ocean and atmosphere (National Oceanic and Atmospheric Administration, NOAA), States this coronal mass ejection will pass by mercury and Earth, and therefore will not threaten significant geomagnetic storms, reports Rus.Media.

A small flow of the solar wind crashed into the Earth’s magnetic field 7 Oct. Another stream of gaseous material should reach our planet later in the evening on 10 and 11 October, which will lead to the appearance of polar geomagnetic storms and auroras.

Geomagnetic storms can increase the density and change density distribution in the upper layers of the atmosphere, which will result in additional aerodynamic resistance to movement of satellites in low earth orbit. Local heating also creates strong horizontal inhomogeneity of the density of the ionosphere, which can change the path of radio signals and cause errors in determining the location by means of GPS. Although these geomagnetic storms are accompanied by beautiful auroras, they can cause damage to navigation systems such as Global Navigation Satellite System (GNSS), and to cause dangerous electric currents in power grids and pipelines.

NOAA reports that the solar activity in October is going to be very low during the month is expected to appear only one event, the C-class with relatively low probability. Increased geomagnetic activity expected 15, 26 and 27 October.
