AB: We present a statistical study on reconnection events performed using the Double Star TC1 plasma and magnetic field data. We examined about 250 magnetopause crossings occurred during the first year of the mission in the 06 - 18 LT interval. The Walèn relation was used to identify reconnection signatures at the magnetopause. We studied the occurrence of reconnection in relation to the local magnetosheath parameters such as the local Alfvèn Mach number, the plasma beta and the magnetic shear angle. Reconnection jet properties are discussed in the framework of the large scale configuration of the merging between the magnetosheath and magnetospheric fields.
