Summary (maximum 250 words)

We apply an automated procedure for Coronal Bright points identification inside coronal holes to AIA/SDO images observed at 193 A. The positions of the bright points are tracked to study the profile of solar rotation inside coronal holes. Rotation profile could provide information to estimate coronal holes anchoring depths. We find that the latitudinal profile of solar rotation inside coronal holes reflects mean rotation profile of photospheric magnetic fields, that suggest that coronal holes are a near surface phenomenon.
