An unusually shaped coronal hole has been detected on the Sun
A large coronal hole of a rare configuration, similar to a single one, has formed on the Sun. This was announced on January 16 at the Laboratory of Solar Astronomy at the Institute of Space Research (IKI) of the Russian Academy of Sciences.
"Another large coronal hole has formed on the Sun, this time with a rather unusual shape. It resembles a huge inverted number "1", although if you have imagination, here, as in the clouds, you can probably see a lot of things. The height of the "figure" is about 1 million km," says a message posted on the laboratory's Telegram channel.
Scientists noted that the active appearance of coronal holes is associated with a decline in solar activity after passing the peak, which occurred in October–December 2024. This process began in the first months of last year and then caused a noticeable increase in the number of magnetic storms. According to experts, the current state of the Sun indicates the continuation of this trend. The laboratory predicts that in 2026 the number of magnetic storms may exceed the figures of previous years.
On January 15, the IKI RAS reported that the second strong M-class flare occurred on the Sun in 2026. In addition, the laboratory indicated that, despite the definition of the outbreak as medium in strength, its impact on the Earth was not felt. The following events are expected to occur within 1-2 days, although forecasts based on numbers have no scientific basis.
