(transient astronomical event)
(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 detected by observing an 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:

Transients can be categorized by the type of EMR under which they were observed, radio, infrared, etc. Some terms;
