X5.8 did produce a CME and ejected high energy protons. Very high energy. >100 mEv protons already being measured and climbing. Notice the green line in the image. Way too early to tell how this is going to effect the current situation, but it certainly will not help and likely will make the radiation storm already in progress worse. Likely much worse, time will tell.
