873 Our Sun Goes Spotless During Storming

23 Feb 2026This week’s space weather is relatively calm, with a few minor solar storms and fast solar wind from a coronal hole. However, this calm is expected to change as a large active region, previously known as region 4366, rotates back into view in a few days. This region is expected to increase the risk of radio blackouts, solar flux, and radiation storms.The equatorial anomaly is causing increased scintillation risk off the east coast of South America, particularly in Brazil. Aurora activity is also increasing at high latitudes due to solar storms, which will likely lead to higher scintillation risk and potential radio blackouts in the coming days. While the current solar flux is low, it is expected to increase, potentially leading to more significant radio blackouts and a slight increase in radiation storm risk.
