When and where the sun illuminates the bottom of the deepest wells

(ORDO NEWS) — It seems that when the Sun moves, it always passes exactly above our heads, but this is not so. Even at noon, light does not fall to the bottom of deep wells most of the time of the year.

If standing at the bottom of a deep well you hope to see the Sun, then we hasten to disappoint you – this can be done only a couple of days a year

The trajectory of the movement of the Sun during the day can vary depending on the geographic location and time of year. Most often, the Sun does not move exactly above our heads, but at an angle, so all objects cast a shadow. For the same reason, the bottom of very deep wells remains in the shade.

But there are days when light can reach these depths. To understand when this happens, we need to discuss two basic concepts: zenith and climax. Zenith is the point in the sky that is exactly above your head. And the culmination is the highest point on the celestial hemisphere through which the Sun passes on its way during the day.

Zenith and climax often do not coincide, but when they do, the sun’s rays can reach the bottom of even the deepest pits and wells. And it happens in different places at different times. For example, at the equator, the climax coincides with the zenith during the equinoxes – March 20 and September 22-23 (depending on the year, this year – the 23rd).

At the latitude of the northern tropic, the sun will look at the bottom of the wells during the summer solstice on June 20-21 (this year – the 21st), and at the latitude of the southern tropic – during the winter solstice on December 21-22 (on the 21st of this year).
