Abstract

That a magnetic reconnection process occurs in a flare impulsive phase is reported in this letter, and together with the process an accompanying inflow is observed for the first time. The observations strongly suggest some forms of interaction between the two loop systems, and the process is also a strong suggestion of an inverse Y-type neutral line formation.
