Aurora Australis

Aurora Australis

It looks like sunset but isn’t. The strongest solar flare (X9.33) of solar cycle 24 erupted on 6 September 2017. Although the responsible sunspot region 2673 was not right in front of the earth when it happened, the coronal mass ejection arrived the earth on 8 September 2017 and the southern lights (Aurora Australis) reached Margaret River region in Western Australia. The photo was taken at approx 34° 30′ S where is closer to Equator than Tokyo (approx 35° 40′ N) is. Thanks for the location of south magnetic pole!
