Ok,so it is definitely a signature [link to www.swpc.noaa.gov] <--- 7 Day Plot,and the 3 Day [link to www.swpc.noaa.gov] I think it began just over 24 Hours after our Sun entered Ophiuchus,but officially in Scorpios,in Scorpios there is the Messier Object 4(M4)and within that a Millisecond Pulsar with a rate 10 Times faster than the Crab Nebula at 3 Milliseconds(3000 Times a Second)

But it is most probably just the Sun,afterall : )
