Sun emits multiple M-class and X2.4-class solar flares and CME toward Earth

9 articles · Updated · Forbes · Apr 24

Five M-class flares on April 23 and a rare X2.4-class flare on April 24 triggered a coronal mass ejection (CME) tracked by NASA’s Solar Dynamics Observatory heading toward Earth.
NOAA forecasts a possible G1-class geomagnetic storm on April 26 as the CME may graze Earth, potentially making northern lights visible this weekend. More solar flares are likely through the weekend.
Recent X2.5-class flares caused radio blackouts over the Pacific and Asia, but their CMEs are unlikely to impact Earth. The sun remains in a waning solar maximum, with strong solar activity and aurora displays still possible.

Beyond radio blackouts, what are the hidden dangers these powerful solar flares pose to us?

As the sun's cycle wanes, was this X-flare barrage a final, powerful grand finale?

Could the sun's recent glancing blow still spark spectacular auroras in unexpected places?
