The astronomical phenomenon of `solar threads` was observed in the skies of Jordan.

Ajloun – Photographers in Ajloun Governorate documented a remarkable astronomical phenomenon during sunset, which was the appearance of what is known as “solar filaments” inside the sun’s disk, in the form of a dark line extending and clearly visible to the naked eye through lenses.

These threads appeared as a dark structure within the sun's disk, in an unusual sight that coincided with a clear distortion in the shape of the sun as a result of strong light refraction in the layers of the atmosphere, especially with high humidity levels on the western horizon.

Experts point out that “solar filaments” are originally phenomena known in astronomy, scientifically known as filament structures, which are clouds of plasma that are relatively cold compared to the surface of the sun, and appear dark when viewed in front of the sun’s disk due to their absorption of light.

The appearance of these filaments with the clarity that has been observed is relatively rare, and often requires special observational conditions, such as a decrease in the intensity of the sun’s brightness at sunset and the presence of atmospheric layers that reduce the intensity of the radiation, allowing fine details within the disk to be distinguished.

The strong atmospheric refraction also contributed to amplifying and distorting the scene, making the string appear longer and more pronounced than usual.

This phenomenon is a unique opportunity for astronomy and photography enthusiasts to observe minute details of solar activity, especially at sunset times, which allow for a clearer view of some solar structures without the need for very advanced equipment.
