A Light Curve is the shape of the graph of the changing Intensity of light (or other Electromagnetic Radiation (EMR)) from a Transient (e.g., Supernova (SN), Transit, Gravitational Microlensing). The curve varies by Wavelength or band. Study of these curve(s) can reveal information about the event and the object(s).
