Don’t look now, however the solar has a giant dot on it. Like, actually, do not look. You may completely harm your eyes.
At virtually 5 instances the diameter of Earth, sunspot AR3190 is an attention-seeking blob on the floor of our star — so huge you may at the moment see it at any time when the solar is shining. However do not give into the temptation to gawk until you may have a pair of eclipse glasses or goggles, ideally ones licensed by the Worldwide Requirements Group(Opens in a brand new window) (ISO).
And by the best way, it’s a superb time to refill on eclipse glasses as a result of they have a tendency to get costly within the weeks earlier than a photo voltaic eclipse, and there’s one approaching April 8.
So what’s the take care of this big sunspot?
At first of the present photo voltaic cycle — the solar’s roughly eleven-year sample of only-somewhat-understood(Opens in a brand new window) magnetic phenomena — astronomers predicted(Opens in a brand new window) that the height 12 months for photo voltaic exercise akin to sunspots can be 2025. It’s solely 2023, and we’re experiencing extraordinary ranges of photo voltaic exercise, together with spectacular eruptions of plasma(Opens in a brand new window), and fairly a number of huge spots — although not one of the others are almost as giant as AR3190. Sunspots like this are uncommon, however removed from exceptional(Opens in a brand new window).
Does this sunspot pose any hazard?
This sunspot most likely poses no precise hazard, but it surely does have an honest probability of, effectively, exploding.

When a sunspot this measurement explodes, one can anticipate a launch of vitality known as a photo voltaic flare. Astronomers anticipate that AR3190 would produce an “X-class” flare, probably the most intense variety. X-class flares ship issues like radio waves, X-rays, and gamma rays out into house on the velocity of sunshine. When Earth will get hit by a powerful flare, the outcomes will be good issues like lovely auroras at northern and southern latitudes, but additionally radio blackouts, satellite tv for pc harm, and energy grid disruption.
A sunspot explosion will also be accompanied by a coronal mass ejection (CME), which is a comparatively slower ejection of particles from the solar’s “corona” — its environment, mainly. CMEs additionally trigger lovely auroras and still have the aptitude to disrupt communications and knock out energy.
But it surely’s anybody’s guess if any of it will occur earlier than AR3190 rotates out of view — which may even cut back the potential for the following actions to trigger issues on Earth.
