Abstract: Detection of individual modes of oscillation near a 5-min period is proposed, based on the comblike signature which is similar to that found in the sun. The mean peak amplitudes of the strongest individual modes are 75-120 cm/s, and the mean separation between alternate modes is 55.3 +/- 3.6 micro-Hz. Apparent modal lifetimes are on the order of 2 d, but we suggest this may be caused by the interference of adjacent modes.
