(A) In general.--The term ``temporarily non-attributed objects'' means the class of objects that temporarily resist prosaic attribution by the initial observer as a result of environmental or system limitations associated with the observation process that nevertheless ultimately have an accepted human origin or known physical cause. Although some unidentified anomalous phenomena may at first be interpreted as temporarily non-attributed objects, they are not temporarily non-attributed objects, and the two categories are mutually exclusive.
[...] includes--
(i) natural celestial, meteorological, and undersea weather phenomena;
(ii) mundane human-made airborne objects, clutter, and marine debris;
(iii) Federal, State, and local government, commercial industry, academic, and private sector aerospace platforms;
(iv) Federal, State, and local government, commercial industry, academic, and private sector ocean-surface and undersea vehicles; and
(v) known foreign systems.

(C) The Collection shall consist of record copies of all Government, Government-provided, or Government-funded records relating to unidentified anomalous phenomena, technologies of unknown origin, and non-human intelligence (or equivalent subjects by any other name with the specific and sole exclusion of temporarily non-attributed objects)
