Under the beams
A planet is under the beams when it is roughly eight to seventeen degrees from the Sun, too close to be easily visible but not close enough to be called combust.
It is the outer of the three solar zones, and the mildest. Classical texts treat it as a planet working quietly rather than one overpowered, and it is often noted alongside a planet's heliacal rising or setting.
Our reports mark all three zones by their measured distance, so the label always follows the arithmetic rather than an impression.
Frequently asked
Where exactly does under the beams end?
Most sources put the outer edge near 17 degrees, the point at which a planet becomes visible again in twilight.
Is it a debility?
A mild accidental one: it describes visibility and voice, not essential dignity.
