title: Daily solar data and sunspot region summary of 23-24 solar cycle

description: This dataset contains records of daily solar data as well as data collected from magnetic classes... This dataset was assembled with data from ftp://ftp.swpc.noaa.gov/pub/warehouse/. The date the data was assembled is 2017-01-15 (yyyy-mm-dd). The original data source is provided by the Space Weather Prediction Center - SWPC, which is linked to the National Oceanic and Atmospheric Administration - NOAA from US Department of Commerce. Data description: <strong>radio_flux_10.7cm</strong>: the solar radio flux at 10.7 cm (2800 MHz) is an indicator of solar activity. It is also called the F10.7 index and is one of the longest running records of solar activity. Radio emissions originate high in the chromosphere and low in the corona of the solar atmosphere. <strong>sesc_sunspot_number</strong>: it refers to the number of sunspots computed on a given day. Also called Wolf's number of sunspots, it is given by R = k(10g + s), where k is a scalable factor indicating the combined effects of observation conditions, g is the number of active regions and s the number of sunspots in all these groups. <strong>sunspot_area</strong>: it refers to the sum of the corrected area of all observed sunspots. It is measured in units of millionths of the solar hemisphere. <strong>goes15_xray_bkgd_flux</strong>: it corresponds to the daily average background X-ray flux that is measured by the SWPC primary GOES satellite. To calculate this value, sensors register 24 X-ray measures for a given day, one for each hour. Then, the SWPC creates 3 groups of periods of 8 hours. For these groups, the SWPC registers the lowest values of flux, creating 3 minimal values, one for each group. Then, they calculate the average between the minimum values of the first and the third group. After the average calculation, they must compare this value to the minimal value of the second group. The minimum value from the last comparison gives the result of the X-ray background flux. <strong>mwl_alpha</strong>: binary attribute indicating the presence of apha magnetic class in any observed spot. <strong>mwl_beta</strong>: binary attribute indicating the presence of beta magnetic class in any observed spot. <strong>mwl_gamma</strong>: binary attribute indicating the presence of gamma magnetic class in any observed spot. <strong>mwl_beta_gamma</strong>: binary attribute indicating the presence of beta-gamma magnetic class in any observed spot. <strong>mwl_delta</strong>: binary attribute indicating the presence of delta magnetic class in any observed spot. <strong>mwl_beta_delta</strong>: binary attribute indicating the presence of beta-delta magnetic class in any observed spot. <strong>mwl_beta_gamma_delta</strong>: binary attribute indicating the presence of beta-gamma-delta magnetic class in any observed spot. <strong>mwl_gamma_delta</strong>: binary attribute indicating the presence of gamma-delta magnetic class in any observed spot. <strong>c_class_flares</strong>: number of c class flares observed. <strong>m_class_flares</strong>: number of m class flares observed. <strong>x_class_flares</strong>: number of x class flares observed. The data collected refer to the period between january 01, 1997 to january 15, 2017.
