Traveling Waves In Network Bright Points

One of the main features of the quiet solar chromosphere is the Network Bright Points (NBP), formed by the emerging magnetic flux, at the boundaries of supergranular cells. Triggered by the motions of magnetic loop foot‐points, at the top of the convection zone, MHD waves propagate inside the NBP’s. Using SSW IDL routines and wavelet analysis of series of images in four bandpasses (CaII K3, Mgb1‐0.4, Mgb2 and Ha core) we detected these MHD wave modes. The observations have been analyzed using cross‐correlation techniques and we have drawn conclusions on wave propagation and mode coupling.
