Solar wind faster than 500 km/s from this coronal hole at the Sun caused the strong beautiful auroras during two last days (without any geomagnetic storms).
People can watch in different countries - e.g. in Norvay -

This coronal hole is rather wide, so we'll be able to watch auroras during next nights also.
