Ionospheric effects of the 2017 US Solar eclipse observed using a global network of GNSS receivers
I'm feeling quite happy about how the observation turned out, because I've also played a small role in producing these measurements. Back in 2015, I wrote a new TEC bias determination algorithm for the MIT Haystack Observatory GPS TEC data product, which improved the quality of the maps.
