DESCRIPTION:Dr. A. Lopez Ariste - IRAP\, CNRS UMR 5277\, Toulouse\, F\nDis
 locations\, or singularities in the phase of a wave\, are ubiquitous featu
 res of waves. Much studied in light or sound\, we observe and study them i
 n magnetohydrodynamic and Alfven waves in the solar plasma. We have found 
 them in sunspots and in the corona. Associated to those dislocations we ha
 ve also observed superoscillations\, where the wave oscillates faster than
  its highest Fourier frequency. Higher frequency means higher dissipation 
 which means effective heating of the solar corona
