<p>This dataset contains samples of solar flares measurements of classes X, M, C and B.</p>
<p>For clarification, the flares are classified as follows:</p>
<ul>
<li>Class X: flares <span class="math-tex">\(>10^{-4} watts/m^{2}\)</span></li>
<li>Class M: <span class="math-tex">\(10^{-5} watts/m^{2} <\)</span>flares <span class="math-tex">\(<10^{-4} watts/m^{2}\)</span></li>
<li>Class C: <span class="math-tex">\(10^{-6} watts/m^{2}<\)</span>flares<span class="math-tex">\(<10^{-5} watts/m^{2}\)</span></li>
<li>Class B: <span class="math-tex">\(10^{-7} watts/m^{2}<\)</span>flares<span class="math-tex">\(<10^{-6} watts/m^{2}\)</span></li>
</ul>
<p>This dataset was assembled with data from https://www.spaceweatherlive.com/en/solar-activity/top-50-solar-flares</p>
<p>The date (yyyy-mm-dd hh:mm:ss) the authors assembled the data is 2017-11-14 13:48:37</p>
<p>The original data source is the National Oceanic & Atmospheric Administration (NOAA), U.S. Departement of Commerce.</p>
<p>Data description:</p>
<ul>
<li><strong>Class</strong>: Class of the flare: X, M, C or B</li>
<li><strong>Date</strong>: Date of occurence in yyyy-mm-dd format.</li>
<li><strong>AR</strong>: Active Region ID attributed by NOAA.</li>
<li><strong>Begin</strong>: time the flare begins in hh:mm:ss format.</li>
<li><strong>Max</strong>: time the flare reaches its max value in hh:mm:ss format.</li>
<li><strong>End</strong>: time the flare vanishes in hh:mm:ss format.</li>
</ul>
<p>The dataset has 2,256 tuples divided as follows:</p>
<ul>
<li>171 tuples with X class flares data (7.58%).</li>
<li>572 tuples with M class flares data (25.35%).</li>
<li>767 tuples with C class flares data (34%).</li>
<li>746 tuples with B class flares data (33.07%).</li>
</ul>
<p>The data collected refer to the period between August 25, 1996 and May 29, 2017.</p>
The HighPIDS research group (http://highpids.ft.unicamp.br) use this dataset to apply Deep Learning algorithms to classify magnetograms of the Sun.
