Inouye Solar Telescope is currently acquiring first science data as part of its Operations Commissioning Phase. High-resolution\, fast-cad ence imaging in the chromospheric Ca II K filter of the Visible Broadband Imager reveals signatures of bright arches emanating radially from the loc ations of G-band bright points. The G-band bright points denote small-scal e magnetic elements harboring strong magnetic fields (~kGauss). Comparison with 3-D simulations suggest that the traveling bright arches are acousti c waves or shock fronts\, triggered by the movements of magnetic elements. Inspecting several examples of the events we indeed see the photospheric bright points changing their appearance and position\, indicating either a horizontal movement\, perhaps swaying\, or rotation and seem to be the so urce location for the bright arches.\n\nhttps://meetings.aip.de/event/24/c ontributions/316/ LOCATION:Haus H\, Telegrafenberg URL:https://meetings.aip.de/event/24/contributions/316/ END:VEVENT END:VCALENDAR
