The asteroid displayed a period of 7.367 0.005 hours and a brightness change of 0.25 0.02 in magnitude.

As the alignment changes, the source's apparent brightness changes, and this can be monitored to detect and study the event.

As a star moves toward or away from us, its apparent brightness changes.

The points at which image brightness changes sharply are typically organized into a set of curved line segments termed edges.

The asteroid displayed a period of 24.60 0.05 hours and a brightness change of 0.30 0.02 in magnitude.

Short, potent and invisible, these rays account for most of the brightness change and have significant effects on Earth in addition to direct heating.

It is a semi-regular variable star that has its brightness change by 0.2 magnitudes over an ill-defined period.

It is a semiregular pulsating variable and its brightness changes over a range of 0.56 magnitudes with a period of 119 days.

The mechanism of brightness changes probably involves relativistic beaming of jets pointed nearly directly toward us.

The craft's infrared detectors might also catch brightness changes.
