Seriously: All we can do is watch these insane size explosions shooting
out from the SUN.

"Massive CHUNKS" of particles? Sheesh, get a clue. It's magnetized plasma (read electrons and protons). There are no "massive chunks".


The massive chunks of particles travel at MILLIONS of MILES PER HOUR,

MILLIONS of miles per hour? Well, maybe 2 million miles per hour.

and if one blew off toward earth, we'd be toasted into the Stone Age!

Again, there are no chunks! There is no "one chunk" of the sun being ejected. It's ionized gas. It's not "hot" so we wouldn't get burned or "toasted". It would likely scramble a bunch of electronics and we'd have borealis light shows.

And the latest ejecta didn't "just miss earth". It was blown out on the far side of the sun away from earth.

I nominate this post for the highest density of misinformation I've ever seen.

Solar storms may cause blackouts and other things, short of blasting us into the stone age. :think:

NASA and The National Academy of Sciences are urging the nation's public utilities and Federal government to create back-up systems for power grids and satellite communications before strikes. NASA predicts that a super storm would strike "like a bolt of lightning" that would change the earth's magnetic field so that everything from car navigation systems, cell phones, computers, banking systems, and air travel would be shot.

In fact, anything that relies on electricity as a power source could be incapacitated within minutes. Not only would the bill to fix the damage cost billions, the loss of electricity around the planet would plunge some societies back to the pre-industrial era.

This is also incorrect. It's possible that things with solid-state circuitry would be affected, but electronic equipment manufactured before transistorized and integrated circuits would not be affected. Any automobile without electronic ignition, i.e. most pre-1970 autos would still work. Any electronic equipment using vacuum tubes would still work. Any motorized device without IC's would still work. We wouldn't be blasted back to pre-industrial or the stone age, we'd be in 1960.

Most people don't have vehicles that old, so that would knock out transportation completely for most people. How long and difficult do you estimate it would be to repair the damage?

That would still be bad. :think:
How many people drive pre-1970 autos?

The last time one that big hit the Earth, it knocked out power in Quebec, damaged some satellites, and could have caused significant ionizing radiation exposure to people on space stations or even high-altitude aircraft.

Not back to the stone age, but major damage and disruption. Not a huge thing as natural disasters go, but still not pleasant.

Not many drive them, but there are a lot of collectible cars that would work. Also, there is the possibility that replacement parts on shelves would not be affected by the solar flare. Possibility, since they don't have power applied to them.

When was that?
Click to expand...

1989, I think. Knocked out huge areas of electrical power in Canada. One significantly greater than the most recent one, could leave tens of millions of people without power for months. (assuming no one has any backup plans, emergency generators, etc)

It's why the FERC released this order:

Also, we have half an hour of warning if a big one is headed our way, and although it would cut power to some people, the utility operators could adjust the system to avoid damage, even as it is today.

We've got longer than that. A day, perhaps more.

Turns out we'll have a little longer warning time than I thought, but not a day:

If all goes well, a new spacecraft should be on its way to space by the time this hits print. The spacecraft involved is the Deep Space Climage ObserVatoRy, generally known under the acronym DSCOVR, and which is a joint project between NASA and the National Oceanic and Atmospheric Administration (NOAA).

DSCOVR (under the name Triana, after Rodrigo de Triana, the first member of Christopher Columbus' crew to sight land in the Americas) was originally proposed in the late 1990s by then-U.S. Vice President Al Gore, who envisioned it as a means to obtain continuous images and climate data of the entire sunlit Earth. It has undergone a significant amount of changes in mission and status since that time, and today has been redesigned as a mission to investigate, as its name implies, the climate of deep space, or, in other words, space weather.

By space weather, we normally mean phenomena associated with the sun such as solar flares and coronal mass ejections (CMEs), as well as the solar wind in general (the solar wind being a stream of charged particles continuously blowing off the sun), and how these all interact with the Earth's magnetic field. ...DSCOVR will be stationed at a gravitationally stable point, known as L1, located one million miles directly sunward of Earth. From that vantage point it will be able to monitor activity on the sun, the near-sun environment, and the space environment at that location, with a complement of three scientific instruments. In the event of a major solar storm headed our way, DSCOVR will be able to provide up to an hour's warning which, while this may seem small, is enough time to give satellite and power grid operators the opportunity to take measures to avoid the worst of the potential damage. The situation can be considered analogous to regular Earth weather satellites which are able to give advance warnings of hurricanes and other major weather systems that are capable of inflicting significant damage to populated regions on Earth's surface.

Thanks for posting that. Using the information in the article we can deduce that the magnetic plasma travels at a speed of 1 million miles per hour. [DSCOVR is a million miles from earth and would provide us with up to an hour of warning time.] However, if we SEE a solar flare on the sun we can see it in 8 minutes, 20 seconds. Then the plasma has to travel 93 million miles.

(Phys.org) —On March 15, 2013, at 2:54 a.m. EDT, the sun erupted with an Earth-directed coronal mass ejection (CME), a solar phenomenon that can send billions of tons of solar particles into space and can reach Earth one to three days later and affect electronic systems in satellites and on the ground. Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO) and ESA/NASA's Solar and Heliospheric Observatory, show that the CME left the sun at speeds of around 900 miles per second, which is a fairly fast speed for CMEs. Historically, CMEs at this speed have caused mild to moderate effects at Earth.

Recent Sun activity has ramped up even further.


It was inevitable that with new observation technologies,
we should be able to catch direct blasts toward the earth from the Sun.

On the 21st we did finally get to see some of this:

On the 23rd we got even more blasts, at slightly slower speeds.

The graphs are the most interesting and alarming data:

New shockwave effects have never been seen before (see 1:50 mins):
