  <dc:description>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:


	Class: Class of the flare: X, M, C or B
	Date: Date of occurence in yyyy-mm-dd format.
	AR: Active Region ID attributed by NOAA.
	Begin: time the flare begins in hh:mm:ss format.
	Max: time the flare reaches its max value in hh:mm:ss format.
	End: 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.</dc:description>
