Tomasz Mielec Posted October 28, 2021 Share Posted October 28, 2021 So SWPC predicted Kp7 maybe be even Kp8 but times its not good for Europe, but always its +/- 6h Link to comment Share on other sites More sharing options...

Jesterface23 Posted October 28, 2021 Share Posted October 28, 2021 Not many of the different models have run yet for the CME. So far one WSA-ENLIL model variant run is Kp6-8. Link to comment Share on other sites More sharing options...

Jesterface23 Posted October 29, 2021 Share Posted October 29, 2021 I'm thinking the minimum possible travel time would be 30 hours. My guess would be 30-40 hours of travel time. Link to comment Share on other sites More sharing options...
Drax Spacex Posted October 29, 2021 Author Share Posted October 29, 2021 (edited) LASCO C2/C3 shows the noisy speckles and spikes of the S1 radiation storm currently hitting the Earth's magnetosphere. GOES-16 Proton Flux > 10MeV for the last 6 hours and continues to exceed this S1 threshold. Dr. Skov says we should expect S1 until CME passes Earth. Is radiation storm strength positively correlated with geomagnetic storm strength (Bz always being the wildcard)? Edited October 29, 2021 by Drax Spacex Dr. Skov says...

Sam Warfel Posted October 29, 2021 Share Posted October 29, 2021 Looks like the majority of it is going southward anyway so it might not be as strong as we thought and definitely not as strong as some people seemed to be worried about Link to comment Share on other sites More sharing options...

I've seen some people say that if it continues flaring and ejecting, we might get a very unlucky 1-2 punch and it poses a big threat. is that true?

Jesterface23 Posted October 29, 2021 Share Posted October 29, 2021 (edited) The 2003 Halloween solar storms were 2 major events, both taking less than 20 hours to reach Earth. What poses a threat is cloud cover not letting us see the aroura. Edited October 29, 2021 by Jesterface23 Link to comment Share on other sites More sharing options...
Hayday Posted October 29, 2021 Share Posted October 29, 2021 (edited) For everyone worrying, it is gonna take more than a Direct X1 to do anything drastic to us, we had minor radio black outs and shitty cell signal today but other than that we will have a great light show in the north! Even two or three in a short span will not take us down, and at this point another one wont compile with the last.

If a severe geomagnetic storm would unfold, there is a risk that satellites get damaged and there will be HF radio interference.

Someone on here talked about G5 in 2015 but for 2015 and 2017 the strongest i was able to find in the archive was Kp8. (What does the + and - mean?) Im just sooo stressed out about my fear that powergrids will collapse 🥲😅 Its just very confusing that it ranges from G1-G3 for Noaa and others are talking about G4-G5. 😕 i cant understand it.

Power grid will be extra monitored during such event so that measures can be taken quickly to prevent damage. That's why there are Space Weather organizations like SWPC, SIDC, MetOffice, ... that provide all industries with the data they need to be prepared. 18 minuten geleden, MinYoongi zei: Its just very confusing that it ranges from G1-G3 for Noaa and others are talking about G4-G5. 😕 i cant understand it.

A slight change in solar wind speed in their calculations can lead to a much earlier or later impact and that has also it's effect on storm strength. It's very hard to predict storms accurately so that's why there will always be differences in predictions. And also don't forget that these are predictions, so it can be stronger or much weaker than predicted. Link to comment Share on other sites More sharing options...
HalfFeralHuman Posted October 29, 2021 Share Posted October 29, 2021 Just following on from @Vancanneyt Sander's comments, globally, power-grids are more interconnected than they used to be and that's left the power-grid more susceptible to induced currents by sudden changes in the earth's magnetosphere, as could be caused by a CME. However, super-capacitors have been installed at nodes along the grid in most places to take this kind of hit and in a well designed/maintained power-grid the worst case would be that those blow and you get a fairly run-of-the-mill power outage. The only thing to be concerned about is sensitive electronic equipment if you live in an area with a bad, unstable power-grid. If you regularly get mini-brownouts or surges it's possible a surge might get to the home. In such a case it might be a good idea to unplug any sensitive devices which aren't behind a surge protector of some kind on Saturday. It probably wouldn't be necessary as your differential fuse should trip before any damage was done anyway, assuming you have one which you probably do unless a monkey wired up your home. As said above, this really isn't likely to happen, but if we have to say there's anything to worry about, it's just that and radio interference unless you live in space or are a satellite.

Quick ps: Do you really think the downward activity from Sunspot 2887 is an indicator for another Big Flare? Saw some post on Twitter you liked that confused me. I always thought solar Flares are not predictable, at least not in that way or manner. If that was sarcasm, my autism struck again 😐🥲😂 Link to comment Share on other sites More sharing options...

Nope, the region is losing spots and its magnetic complexity is decreasing, so it's normal that the flares are getting lower. Yesterday there where two small delta spots and now there's none.
