High time resolution photometric scans of chromospheric Ca(+) K are examined for evidence of propagating waves. The scans refer to a quiet area (1 x 7 arcsec) near disk center. Diagnostics include line profile movies, time sequence spectrograms and power spectra. Both upward and downward (reflected) disturbances having lifetimes of approximately 1-2 min are seen.
