Surprise G1 storm, Sunspot region 2529
A surprise minor G1 geomagnetic storm took place last night thanks to a prolonged period where the direction of the IMF (Bz) turned southward. Values as low as -12nT were recorded and this caused massive auroral outbreaks at high latitudes. Vidid naked eye auroral displays were seen from locations like Estonia and Scotland. Even sky cams in northern Germany captured some faint red aurora in the distance.
Current data suggests there is a slight possibility for aurora to appear at the following high latitude regions in the near future
