Abstract
High time resolution (Δt = 10s) photometric scans of chromospheric Ca+ K are examined for evidence of propagating waves. The scans refer to a quiet area (1 x 7 arc seconds) near disk center. Diagnostics include line profile movies, time sequence spectrograms and power spectra. Both upward and downward (reflected?) disturbances having lifetimes, ~ 1–2 minutes are seen.
