"Intense Solar Flare Sparks Radio Blackout and Northern Lights Watch in Pennsylvania"

The Sun emitted a powerful X-class solar flare and another intense burst of radiation over the weekend, captured by NASA's Solar Dynamics Observatory and NOAA's GOES East satellite. Solar flares can cause radio blackouts and pose risks to space launches and spacecraft, but the recent flares are not expected to impact the public. NOAA's Space Weather Prediction Center issued warnings for high-frequency radio users, and NASA's Solar Dynamics Observatory recorded multiple flares and coronal mass ejections throughout the week.
