This database includes a total of 323 flaring ARs (106 M/X-class flaring ARs and 217 C-class flaring ARs ) appearing from June 2010 until December 2022 observed by the SDO/HMI.

Each entry in MagParDB contains the following information:

  • TSTART - flare start time [UT]
  • TPEAK - flare time of peak X-ray flux [UT]
  • TFINAL - flare end time [UT]
  • IXPEAK - peak 1-8 ? X-ray flux [W/M^2]
  • LON - flare heliographic longitude [DEG]
  • LAT - flare heliographic latitude [DEG]
  • ARNUM - active region number
  • Confined/Eruptive - C(confined; not associated with a CME)/E(eruptive; associated with a CME)
  • E_TOTAL - total photospheric free magnetic energy density [erg cm^-1]
  • AREA_HED - area of HED (high free energy density) [CM^2]
  • Flux_HED - total unsigned magnetic flux within HED region [Mx]
  • SHEAR - mean shear angle within HED region [DEG]
  • UJ_MEAN - mean unsigned vertical current density within HED region [mA m^-2]
  • J_TOTAL - total unsigned vertical current within HED region [A]
  • UHC_MEAN - mean unsigned current helicity within HED region [G^2 m^-1]
  • HC_TOTAL - total unsigned current helicity within HED region [G^2 m^-1]
  • GBH_MEAN - mean horizontal gradient of horizontal field within HED region [G m^-1]
  • ALP_MEAN - mean characteristic twist parameter within HED region [Mm^-1]
  • LPIL - length of the polarity inversion lines with a steep horizontal magnetic gradient [Mm]
