The Relation between EUV Brightenings and Dark Mottles in the Quiet Sun

S. Kamio, H. Kurokawa and D. H. Brooks

During the coordinated observation between Hida/DST and SOHO/CDS in July-August 2002, quiet Sun was observed with Hida/DST H-alpha filtergram and SOHO/CDS high cadence (46s) observational program. We found several examples of EUV brightenings in He I and O V associated with elongated jets in H-alpha wing images. We present the tempposter evolution of dark mottles in H-alpha and EUV intensities, and discuss the possible mechanism of EUV brightenings in the quiet Sun network.
