Sunspots are usually not a cause for concern, even if they double in size overnight and grow to be twice the size of the Earth itself. That’s exactly what happened with Active Region 3038 (AR3038), a sunspot that happens to be facing Earth and could emit some minor solar flares. While there’s no reason to worry, it does mean a potentially exciting event could happen – spectacular auroras.
Although astrophysicists consistently point out that sunspots like AR3038 pose no danger to people, that doesn’t stop the popular media from writing scary headlines about them, especially ones that seem to grow quickly. But sunspots like this are all par for the course, according to Rob Steenburgh, the head of the US’s National Oceanic and Atmospheric Administration (NOAA) Space Weather Forecast Office.
He points out that this type of rapid growth is exactly what we expect to see at this point in the solar cycle, the 11-year repeating pattern that started again in 2019. He also points out that sunspots of this kind don’t typically produce the types of dangerous solar flares that could knock out satellites or disrupt power grids. It simply lacks the complexity.

Universe Today video describing when we should be worried about solar flares.
Solar flares occur when the magnetic fields surrounding a sunspot break and rejoin in complex patterns, some of which cause flairs to be ejected out into the solar system. If these hit the Earth, they could potentially cause damage to some infrastructure, especially those reliant on electricity. However, they are much more likely to create spectacular auroras when their ions hit Earth’s own magnetic field.
They are rated in severity, scaling from B (the weakest) to C, M, and X (the strongest). X flares have their own grading system, and the most powerful solar flares, X20, happen less than once per 11-year solar cycle and typically do not face Earth.
The likelihood of an X20 forming due to AR3038 is minuscule, though there was a 10% chance of it creating a less powerful X flare. More likely are M flares, which AR3038 has a 25% chance of developing before it dies down in size and scale, as sunspots typically do.

However, it doesn’t look like any of those flares will be directed at Earth, as AR3038 has rotated back out of view and is no longer facing us. There is another active region, AR3040, which had 6 C-class flares in the last 24 hours. So there might still be a chance of some spectacular auroras if the planet happens to be in the path of one of those C-class flares.
If not, the whole episode with the rapid growth of AR3038 will prove another example of the public being generally concerned about what appears to be a threatening turn of events, but which is quite common and even innocuous. With all the equipment currently set up to monitor the Sun, the general public can rest assured that we’ll have at least some warning before any potentially damaging flare affects our Earth-bound systems. But it might be a while before that happens, so don’t hold your breath.

Uh, no. Today, June 30, there is only a single sunspot of any size on the sun’s visible surface, and nothing facing earth. Why are articles like this posted here?
Well . . . there goes the “inevitable triumph of socialism!”
We’re all gonna die not Ping!.......................
but it has moved since then and so have we ,LOL
Still the best sun in the galaxy though.

Well for some it is a part of current life and history....
For others it is just something to bitch about.
Have a nice day.
SO HO............................
Tragically, this is bad news.
By tragically, I mean representative of those who believe that the Earth isn't moving... /s
So much for Climate Change.........................
I admit, it was a lot of effort to get it pointed right at earth. Definitely took some elbow grease. But I managed it. You can thank me later.🤣
Definitely better than all the others I’ve travelled around
Don’t point that thing at me bro.
Don’t worry about it, just go outside at night.
hopefully focused on California.
