"The largest solar flare ever recorded since satellites started to measure them in 1976 was estimated to be an X40 solar flare which occurred on November 4th, 2003 during Solar Cycle 23. The XRS long channel on the GOES-12 satellite was saturated at X24.86 for 12 minutes by the intense radiation. A later analysis of the available data yield an estimated peak flux of X40 however there are scientists who think that this solar flare was even stronger than X40. A good thing for us was that the sunspot group which produced this solar flare had already rotated largely of the Earth-facing solar disk when the X40 solar flare occurred. A thing to note is that there has not been a solar flare that saturated the XRS channels since the new generation of GOES satellites but it is expected that it will saturate at about the same flux levels."
"Putting the numbers together, it seems that the energy in the flare was twice as large as any flare since. It is estimated as between X40 and X50. An event like may perhaps happen only twice per millennium. However, the real strength of the event is still being discussed. It is also important to note that solar flares cannot really be described by a single number: it depends on energy, hardness of the radiation, proton flux, and direction of the embedded magnetic field. Flares with the same classification can be quite different in their impact."
I have a feeling the "kill shot" would get here so quick we wouldn't have time to react unless you monitored the activity constantly. Prepping ahead of time and having a plan in place if it happens is about the best we can do. I'm not concerned about a kill shot because it'll probably take me out too. Might as well get a front row seat

"The Carrington Event, for example, would by some estimates have registered as an X40 flare"
