Observing astronomical phenomena:

Astronomical phenomenon is a special phenomenon when a celestial body reaches a certain position (objective position) or state. Some astronomical phenomena are hot topics in astrology. In fact, observing celestial phenomena is a good opportunity to study and photograph celestial bodies. For example, the joint observation of asteroid occultation can determine the shape and size of asteroids. For amateur astronomers, observing some specific astronomical phenomena has become a pleasure.
