The Sun released three significant solar flares in a span of less than 24 hours, along with several coronal mass ejections (CMEs) that may impact Earth, potentially enhancing the visibility of northern lights this week.
The eruptions originated from sunspot region 4455, which is currently facing Earth. The first flare, categorized as M9.3, occurred at 9:36 p.m. EDT on June 2, followed by an M7.9 flare at 3:00 a.m. EDT and an X1 flare at 7:28 a.m. EDT, the latter being the most powerful among the three.
These solar events triggered radio blackouts across different regions of the Earth. The M9.3 flare resulted in a moderate R2 radio blackout in parts of East Asia and Australia. The M7.9 flare caused another R2 blackout affecting areas in Europe and Africa, while the X1 flare produced a stronger R3 blackout across parts of Europe and Asia.
Space weather physicist Tamitha Skov remarked on social media, stating, “Region 4455 strikes again! Region 4455 continues to grow in complexity, so X-flare risk will remain elevated over the next 72 hours at least.”
Less than ten hours after Skov’s comment, the sunspot produced the X-class flare. The likelihood of geomagnetic storm activity is increasing as the situation develops.
Aurora chaser Vincent Ledvina has indicated that three CMEs directed toward Earth are being tracked, although their exact paths and speeds are still under analysis. The U.K. Met Office confirmed that the M9.3 flare was accompanied by a fast CME expected to reach Earth on June 4. They are also assessing another potential CME related to the M7.9 flare, while the X1 flare’s effects remain under investigation.
In response to the incoming solar activity, the Met Office has issued a strong geomagnetic storm watch (G3) for June 4-6. They anticipate geomagnetic activity could reach levels between G1 to G3, with a slight chance for isolated severe (G4) conditions if the impacted CMEs exert a stronger force than anticipated.
This expected geomagnetic storm could provide better opportunities for skywatchers, as geomagnetic activity tends to enhance auroras, potentially allowing them to be visible at lower latitudes starting Thursday evening.
Continued observations of region 4455 are essential, as there remains potential for additional strong solar flares in the coming days.
