You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

It is shown that the anomalously rapid damping of coronal-loop oscillations initiated by an external action (a shock wave from a solar flare) is completely explained in terms of the radiative damping mechanism. A coronal loop oscillating with a small but finite (observable) amplitude in an external magnetic field efficiently generates fast magnetosonic modes. As a result, the perturbation energy is completely dissipated during several periods of free oscillations of the loop. The problem is studied in the perfectly conducting plasma approximation. The effect is explained without making any hypotheses about anomalous properties of the plasma inside the coronal loops.
