A powerful solar flare, classified as an X1.2 event, struck the sun on Friday morning, causing radio blackouts in parts of South America, Africa, and eastern South America. The flare was triggered by a sunspot region known as AR 3947 and released a massive burst of energy.
The flare was rated an R3 blackout on the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Prediction Center scale, indicating a “Strong” impact on radio communications. There were no coronal mass ejections (CMEs) observed that could have impacted Earth.
However, scientists predicted that there may be additional minor to moderate radio blackouts throughout the weekend due to activity from the active sunspot regions. A Geomagnetic Storm Watch for a Category 1 storm remains in place, but the chances of viewing the aurora are best at higher latitudes, such as Alaska and Canada.
This event provides an opportunity for people to witness the aurora borealis, also known as the northern lights, which may be visible in lower latitudes due to the solar flare.
