How we can Celebrate or Observe Find a Rainbow Day:

The gap between the primary bow and the secondary bow being called as “Alexander band”
• Twinned rainbow, which appears as just two rainbow arcs with colors in the same order. This happens due to different size of water droplets being reflected, refracted and dispersed.
• Full-Circle Rainbow, which appears to be in circular shape starting  from the ground. So when the observer observes this from the ground. The only upper circle can be seen rather the full circle.
