Keywords:Broken specter, atmospheric optical phenomenon

A Broken specter is magnified shadow of an observer that happens when there is mist that is lit by sunlight. A ring of rainbow colors can been seen around the shadow. It is so difficult to find this specter in everyday life. Therefore, we are trying to find a constant and predictable condition for when and how this specter will happen by recreating this specter in a controlled situation. Also, we are studying this theory and trying to determine whether this condition is based on theory or not. We also observed another atmospheric optical phenomenon such as Choi and Circumzenithal Arc to compare the necessary conditions to see the Brocken specter. In the end, we want to find this specter in nature and estimate what kind of specter will happen.
