[time-nuts] Re: Power grid logging during the eclipse?

[Jeremy Nichols]

I have a monitor at my home in California. It is monitored by a university
in Kentucky. They watch the frequency nationwide. I can ask them if they
saw anything strange during the eclipse.

I also have a Ting monitor that reports to me weekly. It looks for voltage
spikes, dropouts, etc.  I’ll see what the next report looks like.
