Space-time diagrams for the 16 locations marked in Fig. 5, illustrating the transverse oscillations of the spicules. The panels show SST Hα −0.8 Å, Hα line-center, and Hα +0.8 Å observations, as indicated. The horizontal axis represents time, and the vertical axis shows the transverse displacement (distance) in megameters. The dashed red curves represent polynomial fits to the transverse motion of the spicule axis. The numbers in the lower-left corner of each panel correspond to the slit identification numbers shown in Fig. 5. The derived wave parameters are listed in Table 1.
