Specialists from the Laboratory of Solar Astronomy reported that on June 28, the largest group of sunspots since the beginning of 2026 was recorded on the Sun's surface. Its area reached 1,190 conventional units, exceeding the previous record for this year. This was reported by Qazaqyia.kz citing Kursiv Media.
As noted by the Laboratory, the previous largest region observed in February was slightly smaller – about 1,100 units – but it was the one that caused a powerful X8.1-class solar flare and became one of the most active in recent years.
The new region, numbered 4478, is currently relatively calm. Scientists believe that active processes are occurring inside it and energy is accumulating, but there are no signs of strong flares yet. Occasionally, small plasma clouds are ejected from this region into space.
Astronomers noted that two such ejections could reach Earth on June 30 and July 1, 2026. According to their forecast for June 30, magnetic fluctuations are possible from morning until noon, which could escalate into a G1 magnetic storm. By evening, the magnetosphere should calm down.
Earlier, Kursiv reported on a magnetic storm recorded on June 13.
Doctors advise limiting intense physical activity and avoiding stressful situations during peak activity periods. It is recommended to drink more clean water to maintain normal vascular tone and strictly adhere to a sleep schedule. People with chronic cardiovascular diseases should keep their prescribed medications on hand.
