People from some parts of Australia and New Zealand were amazed at the beautiful and colorful aurora australis that illuminated their night skies last Sunday, May 28, 2017. It appeared above Tasmania in Australia and New Zealand's South Island.

Dave Reynolds, a landscape photographer, captured images of the aurora australis in a small town of Hobart in Tasmania. He described the sight as beautiful and incredible. He added that it brought him a lot of joy.

Mr. Reynolds told the BBC that it appeared to the naked eye as a very bright white light for nearly two minutes as it moved across the sky. "It was so bright I actually started chuckling to myself."

Aurora is also referred to as Northern or Southern Lights or polar lights. It appears because of the disturbance of the solar wind that interacts with Earth's magnetic field and atmosphere. The solar wind is a stream of charged particles escaping the Sun.

Aurora australis could also be forecasted using the planetary index or Kp numbers that are a measure of geomagnetic activity that heightens on a scale of zero to nine based on the geomagnetic strength. In this aurora that appeared on Sunday, it had a Kp number of seven. This means that it could be seen from Tasmania and the southern end of New Zealand's South Island, according to The Guardian.
