If you are out and about after dark and you are in higher latitudes (meaning towards the poles) northern and southern hemisphere and have clear skies keep an eye out for an aurora. We have had sporadic aurora over the past couple days thanks to a coronal hole on the Sun. Disturbances in the geomagnetic field due to strong earthquakes may be another possible aurora source.
ESA: Earth’s magnetosphere is a region of space dominated by our planet’s magnetic field. The magnetosphere protects Earth from most of the solar wind, a flow of charged particles streaming out from the Sun.
However, some particles are able to penetrate this shield and reach the ionosphere, giving rise to space weather effects, including the beautiful polar lights, or auroras, as well as geomagnetic storms. Space weather has a real impact on our activities on Earth, and poses a significant risk to space-farers – robotic and human alike.
Meanwhile, Sun-watching satellites like the ESA/NASA Solar and Heliospheric Observatory (SOHO), located at the L1 point between Earth and the Sun, monitor coronal mass ejections leaving the Sun and measure the speed of the solar wind 1.5 million km away from our planet, about 1 hour before it reaches Earth.
