Buenas noches, tengo aproximadamente 50 enlaces inalámbricos y a las 7:15pm hora de Venezuela fueron afectados disminuyendo un 75% de su capacidad de transmisión y recepción de datos, conocen algun caso parecido al mio? es que en 4 años no me habia sucedido a pesar de las demas tormentas. Gracias

Welcome sismo2001. Please remember that this is an English speaking forum. Thanks!

I apologize, I didn't see that the translator was active in my browser

Almost 4 hours ago, not much space weather-wise seemed to be happening.

I guess as confirmation, the SIR of the CH has impacted STEREO A with a IMF shock. One interesting CH.

Please explain what this means and where one can see this as well 

The EPAM is the Electron, Proton, and Alpha-particle Monitor on board ACE, which has been located at L1 since around the beginning of 1998. As Adohran pointed out you can see the data from it here on SWL, which is taken from its dedicated site here.

What it means is essentially how many protons and electrons of different energies (describes how fast they're moving) are passing by the craft at a given moment (per a given unit of area). For Earth-directed CMEs there tends to be a slow rise in the protons, which rises more steeply shortly before the CME hits, so it's often used as an indicator that a CME might be on its way.

Did anyone notice that since January last year we get disproportionately large geomagnetic storms from only minor to moderate solarstorms? Could the weakening magnetic field of the earth have anything to do with it?

The strength of solar flares won't always correlate to the strength of solar storms. We've had many X flares that failed to produce CME's at all this year. There are quite a few factors that determine this.

We have also had underperformers relative to NOAA and other projections as well. 

 

What happened in May was 7 cmes canabalizing eachother on their way to earth. The spike yesterday has several reasonable causes (prolonged southward bz prior to impact, possible filament hitting more on the nose rather than glancing blow, etc. etc.). And the spike was very shortlived, showing how robust the earth's magnetic field was in rebounding. 

 

I encourage ya to look at the old magnetic fields threads. The reality is much different than whatever is being presented on tik tok and twitter and youtube
