    <dct:description>&lt;p&gt;We have created a hard x-ray solar flare catalog using short channel wavelength&amp;nbsp;bands of 0.5 to 4 &amp;Aring; from NOAA&amp;rsquo;s Geostationary Operational Environmental&amp;nbsp;Satellites (GOES) X-Ray Sensor (XRS) data for 2003 to 2018.&amp;nbsp;The Where&amp;rsquo;s That Flare (WTF) catalog was developed using an automated&amp;nbsp;algorithm designed to use changes in the derivative of the hard X-ray flux to&amp;nbsp;identify flares. Intended to provide a complete archive of all hard X-ray solar&amp;nbsp;flare events in GOES XRS data, the WTF catalog (novelly for the hard Xray)&amp;nbsp;distinguishes between &amp;quot;simple&amp;quot; single peak flare events and &amp;quot;complex&amp;quot;&amp;nbsp;multi-peak flare events and is sensitive to small flares near the background&amp;nbsp;level. To account for the varying background level of the hard X-ray flux,&amp;nbsp;the detection algorithm dynamically adapts to the local background to detect&amp;nbsp;flares of all sizes and complexities. A statistical analysis of flare characteristics&amp;nbsp;was performed on the WTF catalog investigating correlations between&amp;nbsp;total energy, flare duration, peak flux, peak time, rise time, decay time, as&amp;nbsp;well as characteristics of complex events such as number of peaks per complex&amp;nbsp;event. Frequency distributions of total energy, flare duration, and number&amp;nbsp;of peaks per complex event were also investigated and fit with power laws&amp;nbsp;where applicable.&lt;/p&gt;</dct:description>
