A team of HamSCI researchers led by Nathaniel Frissell W2NAF just published a new article, First Observations of Large Scale Traveling Ionospheric Disturbances Using Automated Amateur Radio Receiving Networks, in the American Geophysical Union journal Geophysical Research Letters. The article looks at an event from November 3, 2017 to demonstrate how a large-scale disturbance moving through the ionosphere can affect the communications distances on the 14 MHz (20 m) amateur radio band. On this day, a 2.5 hour oscillation could be seen in the minimum distance of 14 MHz contacts recorded by the Reverse Beacon Network (RBN), Weak Signal Propagation Reporter Network (WSPRNet), and PSKReporter.
