| Abstract: | We present here an example of solar type U emission for which the negative drift and positive drift branches are emitted at the same location in the corona. This is observed at four frequencies between 435 and 236 MHz. This observation may bring new insights to the dynamics of the corona in relationship with the acceleration process of particles. |
