	abstract = {<p>WSPR data for North America is summarized to examine the impact of a reported x-class solar flare.\&nbsp; The data is divided into distance categories to examine impact on different propagation methods, assuming that distance indicates propagation method. Very short distance (under 100 mile) for non-ionospheric, short distance (100 to 500 miles) for NVIS, medium distance (500-1500 miles) for E-layer propagation and longer distance (over 1500 miles) for F-layer.\&nbsp; Signal to noise ratio is plotted by hour for the date of the flare. The impact of the flare is shown as a sudden decline in SNR for all distance ranges.\&nbsp; While communications under 100 miles were initially presumed to involved non-ionospheric propagation, the flare impact at this distance indicates otherwise. WSPR data is also evaluated for its suitability in propagation analysis, noting strengths and weaknesses.</p>
