Single Arcs

When identifying single arc structures we are looking for a couple of features:
  • A single band stretching across the camera's entire field of view or just a small part section
  • Arcs can have a variety of orientations, east to west, north to south, or a mix of angles
  • Arc can be straight or curved
  • Arc can be green, red, blue, or a mix of the three colours
  • Can appear as a well defined band or have a "curtain effect" where it streams down from the center of the camera towards the edges
