             abstract = "Magnetic reconnection permits topological rearrangements of the 
                         interplanetary and magnetospheric magnetic fields and the entry of 
                         solar wind mass, energy, and momentum into the magnetosphere. 
                         Thus, magnetic reconnection is a key issue to understand space 
                         weather. However, it has not been fully understood yet under which 
                         interplanetary/magnetosheath conditions magnetic reconnection 
                         takes place more effectively at the dayside magnetopause. In the 
                         present study 25 dayside magnetopause reconnection events are 
                         investigated using THEMIS observations in order to find its 
                         dependence on solar wind and magnetosheath conditions. It is found 
                         that the reconnection electric field is proportional to the 
                         interplanetary electric field and inversely proportional to the 
                         solar wind-Alfv{\'e}n Mach number, and that the reconnection 
                         outflow speed is proportional to the solar wind-Alfv{\'e}n speed 
                         and inversely proportional to the magnetosheath plasma beta. 
                         Finally, it is shown that the magnetic shear range with an 
                         occurrence of magnetic reconnection is restricted to large shears 
                         as the magnetosheath flow direction becomes more perpendicular to 
                         the direction of the local magnetopause normal vector. Since these 
                         results refer to fairly typical solar wind-Alfv{\'e}n Mach number 
                         condition they may not apply to more extreme condition.",
