Massive Solar Flare Detected: Potential Impact on Earth’s Atmosphere

Massive Solar Flare Detected: Potential Impact on Earth’s Atmosphere

Satellites operated by NOAA observed a significant solar flare originating from the sun’s bottom on Thursday, March 28. The flare was spotted at 4:56 p.m. ET.

Characteristics of the Solar Flare

The solar flare was classified as an X1.1 flare, indicating its high intensity. X-class flares are the most potent explosions the sun can generate, according to NASA.

Impact on Earth’s Atmosphere

The flare was powerful enough to ionize a portion of Earth’s atmosphere, leading to a deep shortwave radio blackout over the Pacific Ocean.

Description of Coronal Mass Ejection

The solar flare was accompanied by a significant release of plasma known as a coronal mass ejection (CME).

Concerns about Impact

Initially, there were concerns that the CME might collide with Earth, potentially causing geomagnetic storms with adverse effects on satellites and communication infrastructure.

Outcome: Missed Collision with Earth

However, on Friday, March 29, NOAA announced that the CME was likely to miss Earth, alleviating concerns about its impact.

Definition and Cause

Solar flares are massive explosions occurring on the sun’s surface due to the sudden snapping of twisted magnetic field lines.

Recent Solar Events

This solar flare follows a double X-class flare observed on Monday, March 25, which triggered a powerful geomagnetic storm on Earth.

Solar Maximum Prediction

The recent surge in solar activity, including the occurrence of multiple X-class flares, suggests that the sun might have entered its peak activity phase, known as solar maximum.

Comparison with Previous Years

In 2024, seven X-class flares have already been recorded, indicating a higher frequency compared to 2023.
