Apart from a few single low order eigenmodes in small scale mag netic structures\, several simultaneous resonant modes were not found unti l recently. These eigenmodes are associated to small but coherent oscillat ions and require the application of particular spatial filtering technique s to be detected.\nIn this talk I will report and discuss about the detect ion and physical implications of large scale coherent oscillations in a su nspot\, with a spectrum significantly different from p-modes.\n\nhttps://m eetings.aip.de/event/24/contributions/359/ LOCATION:Haus H\, Telegrafenberg URL:https://meetings.aip.de/event/24/contributions/359/ END:VEVENT END:VCALENDAR
