A massive X-class solar flare has erupted from the Sun, causing significant radio blackouts across large parts of the globe – and experts are warning that more could be on the way as the active sunspot turns directly towards Earth.
The powerful eruption originated from sunspot region AR4087 and reached its peak at 4:25am EDT (0825 GMT) on Tuesday (May 14), according to the NOAA Space Weather Prediction Center (SWPC).
This intense X2.7-class flare hit the daylight side of Earth with a wave of X-rays and extreme ultraviolet radiation, causing R3-level radio disruptions across Europe, Asia, and the Middle East, reports space.com.

Solar flares are categorized by their strength – A, B, C, M, and X – with each level indicating a tenfold increase in energy output. This flare’s X2.7 rating makes it one of the most potent observed in recent months.
While Earth was not directly in the path of any potential coronal mass ejection (CME) from this flare – given that the sunspot region is still near the Sun’s edge – scientists are keeping a close eye on developments.
CMEs are large explosions of solar plasma and magnetic field that can trigger geomagnetic storms and even spectacular auroras, especially if they collide with Earth’s magnetic field. Notably, sunspot AR4087 is rotating towards Earth and has already shown signs of volatility. It has unleashed multiple flares within a few hours, including a strong M5.3-class flare just before the X2.7 eruption.

Vincent Ledvina, an aurora expert, sounded the alarm on X. This is getting intense, especially as this active region turns closer into view. This same AR just produced an M5.3 flare a few hours ago. What does this AR have planned over the next days … we’ll have to wait and see,” Ledvina wrote.
The powerhouse Sun has cranked up its game with the most explosive solar flare seen since March, notching a mighty X2.7 from sunspot region AR4086, waving goodbye as it exits stage left. Earth’s tech ecosystems brace themselves once again as the Sun flexes, sending jitters about potential hiccups in communication, travel by the stars, and orbital tech.
Following this solar surprise act, the atmosphere high above Earth was electrified posthaste, wracking high-frequency radio communications with sudden static across wide expanses.
Forecasters at the SWPC are issuing a heads-up that Uncle Sam and globetrotters elsewhere might need to bunker down for more celestial fireworks courtesy of our star, dependent on the whims of sunspot AR4087 as it swaggers into a more Earth-affecting stance.
With Earth in its dance around the Sun and AR4087 acting up, there’s chitchat about Northern Light extravaganzas dipping further south and simultaneously, buzzkill babble about tech tremors and energy edginess.
Eyes are peeled and telescopes trained as scientists stand guard; with AR4087 throwing shade – quite literally – the stakes are high for what’s next in our solar system saga.

Thanks Wes! We should all be aware.

Can these solar flares hurt us? Will this flare emit a harmful type & amount of radiation to all the creatures here, on our planet? How does one prepare/protect against this radiation, electromagnetic energy, and other potentially harmful effects?
I understand the questions I’m posing are more me thinking out loud, than an expectation someone with the answers will somehow magically drop down outa the sky.
So many questions pop up for me as I read over this sun flare article. Interesting.
Thanks Wes. Appreciate this info. Addie

I wonder if this had anything to do with airplane pilots losing contact with control towers for over 90 seconds. That was scary!
