Last night I went out again to take some pictures of the sky. According to SpaceWeatherLive.com there was a 60% chance to see aurora light in Belgium and the Netherlands. The reason why we had the chance to see it at these latitudes is because of a prolonged C9 solar flare which caused geomagnetic storm with a strength of G3/G4 (G3 = strong, G4 = severe).
I was super excited to see some aurora light, but the weather decided to ruine those plans. I already live in a very light polluted area and it was bit foggy, which increased the light pollution even more and ruined it for me to see the aurora lights. However, I was still able to take some nice pictures of the sky.
Maybe better luck next time.
