On July 1st 2019 an unexplained aerial glow is seen emanating from the Chapelle Expiatoire, 29 rue Pasquier 75008 Paris, France. A witness describes it as a dense nucleus: five kilograms of glass, mirrors and circuits orbited by four radiant halos.

It is observed hovering and levitating between 1700hrs and 2000hrs and seems to translate the imperceptible oscillations of sound into light vibration. It is being analysed under the code name A.T.O.M [Audio Trans-Optic Matter]. Concentrated effort is being made by a small group headed by Clara Daguin to research the phenomenon.
