Given the right conditions, large circles or rings can be seen around the moon or the sun which is a phenomenon known as 22° Halo. Ice crystals at high altitudes refract light from the sun and moon. This phenomenon occurs around 5.5-6.4 km above the Earth's surface. Identify in which region of the atmosphere this phenomenon occurs.
