The observations show that the equatorial reconnection site under modest solar wind Alfvén Mach number conditions remained active almost continuously for hours and, at the same time, extended over a wide range of local times (≥4 h). The reconnection jets expanded toward the magnetosphere with distance from the reconnection site. Geotail, closer to the reconnection site, occasionally encountered large‐amplitude mesoscale flux transfer events (FTEs) with durations about or less than 1 min. However, MMS subsequently detected no or only smaller‐amplitude corresponding FTE signatures. It is suggested that during quasi‐continuous spatially extended reconnection, mesoscale FTEs decay as the jet spatially evolves over distances between the two spacecraft of ≥350 ion inertial lengths. %Z https://katalog.ub.tu-freiberg.de/Record/ai-49-aHR0cDovL2R4LmRvaS5vcmcvMTAuMTAwMi8yMDE2Z2wwNjkyMjU %U https://katalog.ub.tu-freiberg.de/Record/ai-49-aHR0cDovL2R4LmRvaS5vcmcvMTAuMTAwMi8yMDE2Z2wwNjkyMjU
