Eclipse
An eclipse is an event during which an object in space moves into a shadow of another.

In 2367, an eclipse occurred on , a planet in the Delta Quadrant. Professor Tolen Ren and his wife, Lidell, witnessed it. 

She remarked to Tom Paris in 2371 that when the eclipse occurred, it was the last time he treated her like a wife instead of a mere friend. She also expressed her uncertainty as to why it had excited him at the time. Paris later recalled this conversation when Tuvok asked him what he remembered of the evening. ()
