Sunspot produces one of the most powerful solar flares of current cycle
A fast-growing dark patch on the Sun's surface kicked off the month of October by shooting out an intense burst of radiation toward Earth. The fast-growing sunspot, a region dubbed AR3842, erupted Tuesday evening,
The sun unleashes its strongest flare this cycle
Yesterday the sun released a huge solar flare, and it's heading toward Earth. It's nothing to worry about since it's nowhere near as large as the Carrington Event of 1859, but it is large enough to give us some amazing aurora.
Geomagnetic Storms Imminent After Strongest Solar Flare This Cycle – And For 7 Years
Solar flares are massive releases of energy from the Sun, associated with sunspots. Sunspots are darker because they are cooler than the surrounding areas but they are a lot more magnetic. The magnetic field there can be about 2,500 times stronger than Earth's own, significantly stronger than the rest of the Sun.
Biggest solar flare since 2017 erupts from sun and Earth is in the firing line (video)
On Oct. 3, the sun released the most powerful solar flare this solar cycle, a colossal X9.05 eruption — and it's heading for Earth.
Largest solar flare in 7 years erupts toward Earth
The largest solar flare of the current solar cycle exploded Thursday, emanating from a sunspot directly facing Earth. Classified as an X-9, this is the most powerful flare of the cycle to date.
Powerful solar flare is headed towards Earth, Nasa says
The flare comes amid increasing solar activity that has brought a run of intense space weather in recent days and weeks. Only a day before, the Sun had released a slightly less powerful but still strong solar flare,
