What's the premier service for tracking these sort of events? Where can I find out the likelihood of getting "hit", and other such projections?

https://www.spaceweatheralerts.com/

It reports all CMEs. You’ll have to do some parsing to work out if we’re going to get hit.

Thinking about it this might be a good saas project.

Probably under the mistaken impression climate scientists don't know about solar cycles.

Under the impression that a lot of climate scientists are quick to disregard the effect variations in solar activity has on climate. To be clear, I'm not denying the effects of CO2, but it still seems possible that the role of CO2 has been exaggerated to some extent. The rise in global temperatures in the past century has coincided with increases in both CO2 and solar activity. And it's probably not a coincidence tha…

The rise in global temperature does not coincide with solar activity:

1) Temperature vs Solar irradiance: https://climate.nasa.gov/climate_resources/189/graphic-tempe...

2) Temperature vs Sun activity: http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/solact.htm...

3) Number of sunspots over the year: https://www.climate.gov/news-features/climate-qa/couldnt-sun...

Not sure why people think scientists would miss obvious things. If a non-specialist can think of a probable objection, chances are the specialist in that field has already study that objection in their intro classes.

Plus: unlike most other measures, we have 400 years of actual observation of the sun's activity. It takes some effort to translate the many ways it's been recorded, and it's not perfect, but the data is there. Climate scientists know the sun had an extended period of low activity through the late 1600s and early 1700s and can form hypotheses.

If we go through another, it's not a big shocker. It's an opportunity to test those hypotheses and develop a better understanding of the impact of solar cycles on the planet's climate. If they're wrong, it's not some grand indictment of climate science. It's just...science. But if they're right and we don't take measures to prevent the worst heating, then we might not get another chance until we recover from the floods and resource wars and the loss of knowledge.

This sort of thing has been weighing on my mind of late. The more I think about it, the more I’m convinced that this is why the stars aren’t full of spaceships. And I’m an optimist. But bear with me. We are at the point where we, as a society/species, are utterly dependent on technology. I live in the centre of Canberra, the capital of Australia, and if the power went out tomorrow, I’m not sure how long the food supp…

"... All transformers are blown. ..." Sure, that's possible. Long powerlines are affected. "... All electronics are fried." What? All? How could that happen due to solar activity? My guess is that even the worst event would leave a ton of working electronics. I don't think mostly anything happens to our cars or laptops, for example.

It depends on the severity of the event and how the electronics are designed.

Any time you have a magnetic field cross a conductor you induce a voltage.

The concern is that small electronics have very sensitive components that operate at low voltages. If there's a voltage spike generated on an internal bus, it could damage components.

Given that a lot of modern electronics are shielded as a matter of regulation and operational necessity, a solar event strong enough to fry all of our electronics would also kill a lot of people directly. It would be an Armageddon-level event.

People can’t start engines.

An event strong enough to disable an ICE vehicle's ignition system will likely have killed anyone who could have used the vehicle.

We can’t pump water.

Most water pumps generally operate on gasoline or other fuel. Electric-powered water pumps is a very recent development.

I mean we got a bad flu and people lost their shit looting toilet paper. Imagine what happens when there’s no power.

Parts of California and most of Texas experience that every year... Most people in India experience multiple power outages each day. No mass looting yet...

Solar flares don't destroy electronics. They induce current in long conductors like power lines. I think the confusion comes from nearby nuclear EMP, which destroys electronics, and high-altitude EMP, which induces currents. Solar flares are basically larger-scale high-altitude EMP.

It is relatively easy to protect the electrical grid, grounding everything and putting surge protectors in front of transformers. The problem is that we aren't doing those protections. Also, the grid is not vulnerable when disconnected; it is possible to turn off the grid for predicted flare and then restart it.

Being lazy about protection is not a universal. Any aliens with more active star would have done the protection from the beginning. Aliens from more quiet stars don't need it.

> without transformers, nobody knows how to build new transformers I feel like you've forgotten that books exist. Literally anywhere with a university is going to have a heap of books documenting how to rebuild modern technological society from scratch.

Sorry, I should have been clearer:

Without transformers, we can’t build new transformers.

Think of the supply chain involved. It all runs on electricity. We’ve built ourselves in to a corner where basically nothing is possible without power.

So yeah, go get that book from the library. Good luck smelting steel.

I wonder what the insurance policy on starlink satellites looks like.

They already lost a few dozen satellites in a previous incident in february 2022. https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/202...

I doubt they'd insure them for this kind of mishap. They'll just launch new ones.

They probably do have third party insurance though for debris hitting earth I guess.

"Complete Metal Working Shop From Scrap Series Set (7 INDIVIDUAL BOOKS)"

Here is the description of the series:

ISBN 1-878087-00-2 The Charcoal Foundry

ISBN 1-878087-01-0 The Metal Lathe

ISBN 1-878087-02-9 The Metal Shaper

ISBN 1-878087-04-5 The Drill Press

ISBN 1-878087-05-3 The Dividing Head & Deluxe Accessories

ISBN 1-878087-06-1 The Sheet Metal Brake

Quote from the site:

Build Your Own Metal Working Shop From Scrap is a progressive series of seven projects including, The Charcoal Foundry, The Metal Lathe, The Metal Shaper, The Milling Machine, The Drill Press, The Dividing Head and The Sheet Metal Brake. Beginning with a simple charcoal fired foundry, you produce the castings for building the machine tools to equip your shop. Initially the castings are finished by simple hand methods, but it isn’t long before the developing machines are doing much of the work to produce their own parts. It does not take long to learn the simple craft of pattern-making and sand molding. Each phase of the projects increase your knowledge and skill. There is no need to look for outside help. You can do it all in your own shop. No complicated math----No exotic equipment required----No large cash outlay. Lots of work to be sure, and some of it can be downright tedious, but the reward will be a practical small scale machine shop that you might never give yourself permission to buy, assuming you could afford it.
