Type II spicules Objective To find the disk counterpart of type II spicules (De Pontieu et al. 2007). Scientific background De Pontieu et al. (2007) found two types of spicules; TypeI -spicules by shock waves and Type-II picules by magnetic reconnection. Especially, the type II spicule was newly found by Hinode and the thorough investigation of its properties is in progress now. The study of the type II spicules is important in the viewpoint of transferring the heat to the corona. We want to find the disk counterpart of type II spicules, with collaborative observation at SST/ TRIPPEL spectrograph (Ca II H) and Hinode. We also do spectroscopy above the limb to determine the width of the emission and look for the absorption close to the limb of type II spicules. As the time scale of the spicules is very short (10-150s), very high cadence images is necessary, in addition to the small region scanning by EIS and coronal temperature imaging by XRT.
