So the much anticipated CME from Oct 13th M1.7 solar flare has gone missing. It was due to arrive last night and spark great aurora shows, but as yet there is no sign of it. Either it was VERY weak, or it is very late. There are some blips on the proton graphs which could indicate a weak CME brushed past earth, but NOAA SWPC had this forecast as a Kp4 event over the course of 12 hours or more. If this CME is late, ok, it happens, but if it is non existent or missed earth entirely. I think they need to re-calibrate their instruments.
We will know more later.
