Russian Lab Reports Two Strong M-Class Solar Flares

The Solar Astronomy Laboratory of the Russian Academy of Sciences reported the detection of two strong solar flares classified as M-class.

The laboratory stated that the Sun experienced a notable increase in activity this week, marked by two sequential M-class solar flares. The first flare, rated M2.6, peaked at 5:46 Moscow time, while the second, rated M6.8, was observed later in the day at 22:29.

Both flares originated from sunspot group number 4473 located on the eastern limb of the Sun, which currently represents the only active region. The laboratory noted that this group also produced several other less intense flares during the same period, making it the most active area since June 3.

Experts indicated that at least one of the flares was accompanied by a plasma emission directed toward space. However, its speed and mass characteristics were insufficient for the emission to reach Earth. They emphasized that these solar events have not yet had a direct impact on space weather but hold statistical and scientific significance.

The laboratory forecasted that sunspot group 4473 will move toward the center of the solar disk in the coming days, positioning itself directly facing Earth by June 25. They did not rule out the possibility that the active region's activity might diminish or that it could disappear during this timeframe.

Scientists highlighted that solar flares can trigger geomagnetic storms affecting power grids, communication, and navigation systems, as well as potentially increasing the occurrence of auroras. Research continues to assess the extent of these phenomena's effects on human health.
