  One of the mechanisms proposed for heating the corona above solar active
regions is the damping of magnetohydrodynamic (MHD) waves. Continuing on
previous work, we provide observational evidence for the existence of
high-frequency MHD waves in coronal loops observed during the August 1999 total
solar eclipse. A wavelet analysis is used to identify twenty 4x4 arcsec2 areas
showing intensity oscillations. All detections lie in the frequency Hz (5-3 s),
last for at least 3 periods at a confidence level of more than 99% and arise
just outside known coronal loops. This leads us to suggest that they occur in
low emission-measure or different temperature loops associated with the active
region.
