  We present observations of a solar quiet region obtained using Hinode Solar
Optical telescope (SOT) in Ca II H line with broadband filter taken on November
2006. We study offlimb and on disk spicules to find a counterpart of limb
spicule on the disk. This investigation shows a strong correspondence between
the limb and near limb spicules (ondisk spicules that historically were called
dark or bright mottles especially when observed in Halpha rather cool line)
from the dynamical behavior (e.g., periodicity). An excellent time sequence of
images obtained near the equatorial region with a cadence of 8 s was selected
for analysis. 1D Fourier power spectra made at different positions on the disk
and above the limb are shown. We take advantage of the so-called madmax
operator to reduce effects of overlapping and improve the visibility of these
hair like features. A definite signature with strong power in the 3 min. (5.5
mHz) and 5 min. (3.5 mHz) oscillations for both places exist. A full range of
oscillations was found and the high frequency intensity fluctuation (greater
than 10 mHz or less than 100 sec.) corresponding to the occurrence of the so-
called type II spicules and, even more impressively, dominant peaks of Fourier
power spectra are seen in a wide range of frequencies and for all places of on
and off disk spicules, in rough agreement with what historical works were
reporting regarding the disk mottles and limb spicules. Also, some
statistically significant behavior, based on power spectrum computed for
different positions, is discussed. The power for all kind of power spectra are
decreasing with the increasing distance from the limb, except for photospheric
oscillations (5 min. or p mode), which show a dominate peak for on disk power
spectra.
