We present preliminary results on a magnetic reconnection event observed by the Cluster spacecraft at the dayside magnetopause. Cluster 3 crossed the magnetopause at (X, Y, Z) = (8.3, 1.3, 4.5) RE GSM while travelling outbound in the northern hemisphere on March 5, 2007. Bursty high speed flows (Vz~250 km/s, Vx~-200 km/s) were observed from 18:55 UT to 19:10 UT. Meanwhile, energetic protons (> 30 keV) and Oxygen ions were observed by the RAPID instrument. During this time interval, the IMF was southward with (Bx, By, Bz) = (-4, 0, -4) nT GSM and the solar wind speed was -400 km/s. Cold plasmashperic materials were accelerated by the magnetic reconnection. The ion pitch angle measured by the CIS instrument changed from 0 to 180 degree, indicating that the direction of the magnetic field changed from northward to southward, i.e., the spacecraft passed the reconnection outflow region from the magnetospheric side to the magnetosheath side. The energy spectra of ions before and during the outflow region crossing have been investigated. The role played by cold ions in the reconnection process has been discussed.
