AURORA SOUTHERN LIGHTS Taken by Minoru Yoneto on May 28, 2017 @ Queenstown, New Zealand

I remembered the solar activity peak period between 1989 and 1990, 2000 and 2001 during taking these pictures.

The Southerns Lights could already be seen during the astronomical twilight. This means this appearing was quite strong.
