Abstract
Observations of solar velocity fields made simultaneously at Mount Wilson and at Kitt Peak with the same size aperture (5 arc-sec) and same position on the disk (± 1 arc-sec) are presented. The object is to clarify whether the short-period oscillations (SPO's) previously reported (Howard, 1967), could be caused by local seeing conditions. The time of onset and general character of the SPO's are found to be well correlated for the two sites, a condition that favors a solar origin. However, because correlation in complete detail did not prove possible, some doubt must remain regarding the source of the SPO's.
