# Motion Right After Separation -> 2003/08/08 Completed
    At 300 seconds after the separation, three monopole antennas of CUTE-I were successfully deployed. The following graphs show angular velocity at near the deployment time. Precise antenna deployment time is 303s. The angular velocity starts to change at 303s. The antennas are coiled around b2-axis(in CUTE_Frame) of CUTE-I, so the antennas deployment influences the rotation around b2-axis. The following graph certainly indicates the effect of antenna deployment.
