Query: Statistical analysis on Dynamic Fibrils observed from NST/BBSO
  observations   We present the results obtained from the analysis of dynamic fibrils in NOAA
active region (AR) 12132, using high resolution H$\alpha$ observations from New
Solar Telescope operating at BBSO. The dynamic fibrils are seen to be moving up
and down, and most of these dynamic fibrils are periodic and have jet like
appearance. We found from our observations that the fibrils follows perfect
parabolic paths at the most in many cases. A statistical measure on the
properties of the parabolic paths showing an analysis on deceleration, maximum
velocity, duration and kinetic energy of these fibrils is presented here. We
found the average maximum velocity to be around 15 km s$^{-1}$ and mean
deceleration to be around 100 m s$^{-2}$. The deceleration observed appears to
be a fraction of gravity of sun and is not compatible with the path of
ballistic at the gravity of sun. We found positive correlation between the
deceleration and the maximum velocity. This correlation is consistent with the
simulations done earlier on magnetoacoustic shock waves propagating upward.
