ConfinedflareDB README FILE ------------------------------------------------------------------------------ This database includes a total of 152 confined flares (not associated with a coronal mass ejection) of Geostationary Operational Environmental Satellite (GOES) class M1.0 and larger that occurred within 45 degree from the central meridian, from June 2010 until June 2019. Each entry in ConfinedflareDB contains the following information: Type ¨C ``Type I" or ``Type II" confined flare ``Type I" flares¡ªatypical confined flares above the filaments. The slipping motions of the flare loops or flare ribbons can be clearly seen. The filament/flux rope is stable and does not seem to be disturbed during the flare. In addition, the low-temperature PFLs observed in the 171 and 304 ? channels are located above the stable filament. ``Type II" flares¡ªtypical confined flares associated with the failed eruptions of the filaments/flux ropes. The main characteristic of this type is the failed eruption of the core filament/flux rope. The filament/flux rope initially rises up during the flare and then quickly slows down. The overlying large-scale arcades are heated and can be observed at the high-temperature wavelength (131 ?). In other words, this type of flares is consistent with the classical 2D flare model.
