A Database of Flare Ribbon Properties from the Solar Dynamics Observatory. I. Reconnection Flux View all abstracts by submitter

Maria D Kazachenko   Submitted: 2017-08-30 12:43

We present a database of 3137 solar flare ribbon events corresponding to every flare of GOES class C1.0 and greater within 45? from the central meridian, from 2010 April until 2016 April, observed by the Solar Dynamics Observatory. For every event in the database, we compare the GOES peak X-ray flux with the corresponding active region and flare ribbon properties. We find that while the peak X-ray flux is not correlated with the active region unsigned magnetic flux, it is strongly correlated with the flare ribbon reconnection flux, flare ribbon area, and the fraction of active region flux that undergoes reconnection. We find the relationship between the peak X-ray flux and the flare ribbon reconnection flux to be IX,peak ~ (Φribbon)1.5. This scaling law is consistent with earlier hydrodynamic simulations of impulsively heated flare loops. Using the flare reconnection flux as a proxy for the total released flare energy E, we find that the occurrence frequency of flare energies follows a power-law dependence: dN/dE~E-1.6 for 1d31< E< 1d33 erg, consistent with earlier studies of solar and stellar flares. The database is available online and can be used for future quantitative studies of flares.
