Answer: "Just under the horizon" generally refers to an object or phenomenon that is not visible, but is very close to becoming visible or appearing on the horizon. The horizon is the line where the sky appears to meet the ground, and objects that are just under the horizon are typically obstructed from view by the curvature of the earth or other objects.

In general, the phrase "just under the horizon" implies a sense of anticipation or expectation, suggesting that something important or significant is about to happen, but has not yet fully materialized or become visible.
