I have all the data on Dec 5-6th CME event. Agreed on all excellent points. ** *Including Software flaws-* I am very familiar with software flaws and TRAIM errors; although that has nothing to do with my Employer or the Oscilloquartz Timing Products.
However, recheck your data for Dec 6th; dont dismiss this CME ; *it was very large.* In fact, this side of the globe picked up one h*ll of a sun-flare; 9 times larger than previous spikes, and in a low-cycle year too. (at first I thought the April 4th media story was a April Fools or hoax- its not) => Does anyone have TIE data for Dec 5~6th to about the 14th? interval of MJDates of (24)54075.8 to about (24)54083 or so? => Can you share TIE data with me? Does that TIE show much walk? Johnny On 4/13/07, Magnus Danielson <[EMAIL PROTECTED]> wrote: > > From: "RadCom Technologies" <[EMAIL PROTECTED]> > Subject: [time-nuts] December 6th?
