Atmospheric optical phenomena are visual effects caused by the interaction of sunlight (or moonlight) with particles and droplets in the Earth's atmosphere. Here’s a list of some notable atmospheric optical phenomena: 1. **Rainbow**: A multicolored arc formed by the refraction and reflection of sunlight in water droplets, appearing opposite the sun. 2. **Halo**: Circular rings of light that appear around the sun or moon due to ice crystals in the atmosphere.
