(observed change in the sky)

A Transient is an observed phenomenon in the sky involving a change, such as the appearance of an astronomical body or a change in its appearance. They are by definition astronomical events, and obviously among those showing an observable change. The natural way to detect them is to observe the same area more than once and note the differences. Some projects, missions, and surveys aim to discover them, for further study.

Numerous observation occurrences and event types fall under the broad category of transients, thus a survey aimed at finding one phenomenon may also yield discoveries of unrelated phenomena:
