No, you didn't see a solar flare during the total eclipse — but you may have seen something just as special
Several media outlets have incorrectly claimed that explosive solar flares were spotted during the April 8 total solar eclipse. But there were no flares during totality, so what did people see?
During the recent total solar eclipse, you may have glimpsed what looked like explosive solar flares bursting from the sun after its fiery corona briefly came into view. But it turns out this was not the case.
However, what you or others may have seen was equally impressive and just as beautiful.
On Monday (April 8), millions of people across North America watched as the moon temporarily blocked out our home star and its shadow raced along the path of totality between Mexico and Canada at more than 1,500 mph (2,400 km/h). The cosmic event, which was also seen from space, was particularly special because of the length of totality — the period when the sun's light was completely obscured — which lasted for up to 4 minutes and 28 seconds.
During totality, some observers saw red dots around the obscured sun. Detailed photos of these dots revealed they were actually plasma, including a particularly large, fiery plume on the sun's southwest limb. As a result, multiple outlets including USA Today and NDTV reported that these fiery structures were produced by solar flares — explosions on the sun's surface that can launch massive clouds of plasma, known as coronal mass ejections (CMEs), into space. Lots of observers also took to social media to share their photos of these "solar flares."
But experts weighed in to point out there were no solar flares during the eclipse.
"There are many (incorrectly) reporting that a solar flare was visible during the total solar eclipse," Ryan French, an astrophysicist at the National Solar Observatory in Colorado, wrote on the social platform X. "This is sadly untrue, and the bright feature seen by millions was actually a prominence. These are longer-lived plasma structures, and not explosive like flares."

Solar activity data backs up French's claim. On April 8, there was just one minor C-class solar flare that ended several hours before totality began anywhere in the U.S., and it did not launch a CME, according to SpaceWeatherLive.com. This flare was also not linked to the large prominences seen during the eclipse.
Unlike solar flares, which eject plasma as they explode from the sun's surface, prominences are plasma structures that remain connected to the solar surface for days or weeks, normally forming a large loop, according to NASA. Prominences can eventually snap and fling plasma into space like a CME, but this didn't happen during the eclipse.
However, in the lead-up to the eclipse, the sun became surprisingly inactive with almost no sunspots, which meant the chances of solar flares occurring were greatly reduced. This solar activity lull is only temporary and is expected to pass by the end of the week, according to EarthSky.com.
