Scientific paper

We are presenting the observations of the active region NOAA 10709 on December, 2004 using 0.12Å~narrow band filter centered around 1.56μm. The observation run was carried out using Dunn Tower Telescope of NSO (SacPeak) with high-order AO system. The averaged angular resolution of this observation is 0.5" or better. These high resolution data in near infrared offer a new view on the photospheric structures of sunspot near opacity minimum. By using the tunable near infrared narrow band filtergram, we are able to construct magnetic field strength map of sunspot. In particular, we will show the magnetic structure of light bridges and umbral dots.
