However, the mechanisms driving plasma flow in these coronal upflow regions and the underlying layers of the solar atmosphere remain open questions. This study aims to understand the mechanisms responsible for plasma upflow at the borders of coronal active regions. To achieve this, we propose coordinated observations involving Solar Orbiter, DKIST, IRIS, and Hinode. Dates: The most important is to provide a coordinated observation between DKIST, Solar Orbiter (high-resolution instrument) and IRIS: start time: 19 October 2024 19:00 UT - end time: 19 October 2024 19:30 UT. It is possible to extend the coordinated observation time to provide a coordination between DKIST, IRIS and Hinode: start time: 19 October 2024 18:00 UT and end time: 19 October 2024 22:00 UT.
