Although it has b een the focus of many observational and theoretical studies\, the processe s involved in the formation and decay of a sunspot penumbra are still not fully understood. I will give a brief summary of recent observations leadi ng valuable contributions to better understanding these processes.\n\nhttp s://meetings.aip.de/event/24/contributions/358/ LOCATION:Haus H\, Telegrafenberg URL:https://meetings.aip.de/event/24/contributions/358/ END:VEVENT END:VCALENDAR
