A gargantuan , hyperactive sunspot that unleashed three X - class solar flares in less than 24 hour last workweek has continued to tumesce and is now signal right at Earth . A period of unsettling smooth suggests that the grow dark temporary hookup could be gearing up for another massive eruption , which could smash into our planet with potentially damaging results , Spaceweather.com report .
macula AR3590 first come out on the sun ’s Earth - facing side on Feb. 18 and rapidly swelled into adark patchseveral time wider than our satellite . On Feb. 21 , AR3590spit out a pair of tenner - course flare — the most powerful case ofsolar flare pass — with magnitudes of X1.7 and X1.8 . On Feb. 22 , the same sunspotunleashed a massive X6.3 flare , the most knock-down solar explosion in more than six twelvemonth .
The sunspot AR 3590 has already unleashed three X-class flares and could spit out more.
All three flares make irregular wireless blackouts on Earth , but none of them launchedcoronal mass ejections(CMEs ) — swarm of magnetised blood plasma that can thrash into our major planet ’s magnetized cuticle as they fly through space . If any of these sizable explosion had launched a CME at Earth , the resulting plasma cloud could have triggered severe geomagnetic storms — disturbances in Earth ’s magnetic area that can allow solar radiation toimpact ground - based infrastructure , triggerstunning auroral displaysandcause satellites to twig back to Earth .
Since the triple X - class flare , AR3590 has continued to grow , almost doubling in size of it . It is now one of the large sunspots of the current solar oscillation , which began in 2019,Spaceweather.com report .
Experts predicted that the macula ’s unstable magnetic field " harbors vitality for more X - class explosions , " but so far , it has managed only a couple of weak M - class flare ( the course below X - class ) since the triple flares break out , Spaceweather.compreviously reported . This suggests the sunspot could be storing free energy for another massive explosion .
AR 3590 has continually grown as it’s moved across the solar surface.
The gargantuan sunspot is currently pointing " almost directly " at Earth , according to Spaceweather.com . So , if another significant X - course flare does explode from the sun and launch a CME , our major planet will be right in the firing line .

AR3590 is now around 60 % the size of themonster macula that birthed the Carrington Event — a massive solar storm in 1859 that is think to be the largest solar storm in show history to hit Earth .
AR3590 unleashed the most powerful solar flare in 6 years on Feb. 22.
If a Carrington Event - degree flarelaunched a CME at Earth today , it could induce long - term kerfuffle to global world power grid and pass over out most of the spacecraft in eye socket around Earth , resulting in trillions of dollars ' worth of damage . AR3590 is not large enough to trigger this character of solar storm , but even if it hurtle a CME that was half as hefty at us — which is possible — it could still cause serious problems .

The recentincrease in the sizing and frequency of sunspots , as well asmore frequent and powerful solar storms , are clear signs that the Sunday is tight approaching the volatile blossom in its some 11 - class Hz , lie with as solar uttermost .
scientist now think that solar maximumcould come within the first one-half of this year , which is much preferably than experts in the first place predicted . It will also likely be much more powerful than scientists ab initio wait .
As a result , there is a adequate hazard that even if AR3590 does n’t chuck anything foul at us , we could still be strike with a supercharged solar tempest at some point in the next few year .
