[time-nuts] Re: Tonga effect on GPS

[glen english LIST]

I work closely with the Australia Bureau of Meteorology , I am the  RF 
Space Weather technical lead. (contractor)

The papers are being readied for publication right now.

Here is one of the papers, NOT Peer reviewed yet

https://www.essoar.org/doi/10.1002/essoar.10510350.1

you can download the PDF free at that page. It's not a closed academic 
paywall (dont get me started)

There was a substantial discussion in the space weather circles. ALl the 
big swinging dongers of the spave weather and physics community have 
been involved

The TEC didnt change too much at distances of 2000km. 'We' have a 
ionosonde at Nuie , which is just over the 0 meridian, not far away.
