High resolution NST data obtained in the blue wing (-0.75Å) of the H-alpha spectral line show the presence of surprisingly numerous small-scale bright emission features nearly evenly distributed over the field of view. While larger features often exhibit association with H-alpha jets, smaller events (size < 0.5 arcsec) are not accompanied by any detectable plasma flows. We will present results from a statistical study of these emission features and discuss life time of these events, size, their distribution relative to the magnetic field and the association with the plasma jets.
