Samples Of Solar Flares Classes, Active Regions And Time Of Occurrence

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