A Ca II sequence capable of observing spicules with medium cadence (~15---20 sec, 2x2 binning OK). To be run during limb PCH pointing period. (If no PCH is available, this should be run on polar-region quiet Sun, after completion of HOP 278 pointing requests.) Pointing should be as close to limb as possible (15''). (3) SOT observations. Ca II spicule limb observations during at least one of the periods of the limb studies, preferable during PCH observations. If no PCH is available, then the preferred target is polar quiet Sun. The objective is to study spicules at the base of coronal plumes, and/or at the base of X-ray jets (Sterling, Harra, and; Moore 2010, ApJ, 722, 1644).
