On the Sun appeared a coronal hole in the shape of a cat
A coronal hole appeared on the surface of the Sun, the outlines of which resemble the silhouette of a cat.
A coronal hole appeared on the surface of the Sun, the outlines of which resemble the silhouette of a cat. This was reported in the Laboratory of Solar Astronomy IKI RAS and ISZF SB RAS.
“The coronal hole, meanwhile, has become a cat. For this, however, the Sun had to turn, — stated in the message.
A coronal hole is a region of the solar corona with open magnetic field lines along which plasma escapes into interplanetary space. Plasma in such areas is less dense and colder than in the surrounding corona, so they appear dark in ultraviolet and X-ray images. Coronal holes are sources of high-speed solar wind flows.
In January 2026, RBC reported that coronal holes began to actively form on the Sun in early 2025, after the peak of the solar cycle. This led to an increase in the number of magnetic storms in 2025 by 60% compared to 2024.
