Jointly Study on Flux Transfer Events Using the Data Observed by TC-1 and Cluster Near Dayside Magnetopause

One of the Double Star satellite TC-1 and Cluster both in the magnetosheath near the dayside magnetopause amount to 25 times from February to April, 2004, when TC-1 in the low latitude and Cluster in the middle or high latitude region. 27 Flux Transfer Events （FTEs） had been detected by these satellite during that interval. This paper analyzed the influence of the transverse component of the Interplanetary Magnetic Field （IMF） on the position at the magnetopause where the reconnection occurs, and searched the evidence of component reconnection. The main results are as follows： （1） when IMF southward component Bz is dominate （｜Bz｜ 〉 ｜By｜）, 87.5% of FTEs were detected at low latitude by TC-1, but when IMF ｜Bz｜〈 ｜By｜, most FTEs （about 84.2%） were observed at middle or high latitude by Cluster; （2） there were a few correlative events （the correlative event means a event was observed by TC-1 and Cluster at low- and high-latitude, successively）, this imply that most of the FTEs which occurred in lower latitude moved along the sides of the magnetosphere toward the magnetotail, only a few of them over the high-latitude; （3） most FTEs detected at middle latitude were not come from the equator, but burn at that region by the mode of component reconnection.
