Explanation:
Last weekend
skygazers at middle and high latitudes around the globe
were treated to expansive auroral displays as a magnetic storm raged
around
planet Earth.
The storm was triggered by a solar coronal
mass ejection associated
with the giant sunspot group cataloged as active region
number 9393.
For example, pictured here in the early morning hours of April 1, the
skies over New Zealand are alive
with "southern lights".
In the wide-angle time exposure, a towering red aurora is visible
suspended above the foreground of a well lit lumber yard, train
station, church steeple and buildings of the city of Dunedin.
On April 2, the
largest
solar flare of the last 25 years also erupted
near active region 9393, but because of its position near the Sun's
edge the effects were largely directed away from
our fair planet.
However, all the recent solar activity underscores the fact that the
solar maximum is still
with us.
