The RBN-WSPRNet Daily Histograms are used to monitor global high frequency (HF) ham radio communications in relation to space weather activity. To monitor HF radio communications, we use data from two separate automated amateur radio monitoring networks, the Reverse Beacon Network (RBN) and the Weak Signal Propagation Reporting Network (WSPRNet). These networks operate continuously and are built, operated, and maintained on a volunteer basis by members of the amateur radio community. For a detailed analysis of a solar flare and geomagnetic storm event using this type of data, please see Frissell et al. (2019). RBN and WSPRNet data have been aggregated and provided by Bill Engelke, AB4EJ, University of Alabama DXDisplay. Visualizations by Nathaniel Frissell, W2NAF, NJIT CSTR.
