The Fall 2017 Lights of the World Fitness Challenge encourages participants to be physically active an average of at least 20 minutes/day.

Week 5, starting September 24 and ending September 30, features the Aurora Borealis, also known as the Northern Lights, that can be seen from many different areas of the Northern Hemisphere. A sister light show, Aurora Australis, can be seen from portions of the Southern Hemisphere. The auroral electrons spiral around the geomagnetic field, producing a wide variety of lights in the sky after dark.

If in an area where the phenomena can be seen, observers may see patches or arcs of light. The lights may appear as curtains while some change constantly. A variety of colors may be visible, including various combinations of red, green, blue, yellow, or pink.

If you are in an area where Aurora Borealis is present, you may be able to hear a hissing or crackling sound if you are about 230 feet above the earth's surface. Have you ever seen this light phenomenon? If so, where were you?

And the light shineth in darkness; and the darkness comprehended it not. John 1:5
