									Northern Lights
   Go Dim
By Ian Wilson & Anders Bogan
                        The Article
   Title: Northern Lights Go Dim
   By: AFP
   When: Tuesday, September 28, 2010
   Who: Those who study at the north pole, and those who live near
    the aurora borealis
   What: Aurora Borealis (northern lights) dimming from past cycles
   Why: This ties in with impact in outer space and the universe
   Where: Last half of this decade
   How: Ionosphere and magnetosphere affected in this; solar winds
    may also be weaker; environmental global issues

   This article talked about the aurora borealis, which is becoming
    more and more rare and also dimmer, and were only available
    during the second half of this decade.
         Background Information
   In the article, the author discussed about the northern lights, or the
    aurora borealis, and its rare occurrence over the last decade, and
    how it has also become more dim. The northern lights, which are a
    blaze of colors and patterns in the sky, occur when solar winds
    crash against the atmosphere and then are drawn to magnetic
    poles. The reactions of the solar winds crashing against the
    atmosphere create havoc among electrons in the atmosphere
    known as the ionosphere and the magnetosphere. Scientists say
    that this phenomenon may have a correlation with less activity in
    the sun. The aurora borealis often follow an 11 year cycle in which
    the phenomena reach to a maximum and then go back down to a
    minimum, and then the cycle repeats. Scientists also say that solar
    flares and sun sports are also quieting down, and the cycle of
    maximum and minimum may also be affected while the cycle is
    occuring.
                    Bias/ Impact
   This article is not biased, and does not have any
    opinions or statements that lead to one side or theory.
    The author(s) write in such a way that provides an open
    minded opinion and a description that multiple sides of
    the story would all agree on.
   The impact of this article is international. However, it
    may just be involving the north side of the world,
    because the northern lights of course come from the
    north pole. This may also affect the south side of the
    world/ the rest of the world because it can hint activities
    in the sun, and gives hints to what’s going on in the rest
    of the universe.
     Further Decision Influence
   Because of the information in this article,
    this may link to environmental harm in the
    world. If the sun activity or universe
    activity is affected and this correlates with
    global warming or environmental neglect,
    then worldwide actions may be taken and
    the policies we have currently may be
    affected, and that protecting the
    environment would be a more important
    decision than before.
      How it’s related to science
   This article is related to science in many ways. First, it’s
    related because it has to do with the atmosphere and
    reactions with electrons. The ionosphere and
    magnetosphere previously mentioned have to do with
    the environment and how the world functions. Second,
    this article is related to science because it involves the
    north pole, and there are scientists that study and
    observe the north pole, and this is a big concern for
    those studying at the north pole. The northern lights
    may also have a correlation of something that may
    happen to the north pole in the future. This is how the
    article is related to science.
