[20.03] High Resolution Observations of Complex Magnetic Structure in Active Region NOAA 10375

We observed the dynamics, spatial distribution, and temporal evolution of magnetic fields in active region NOAA 10375 using high resolution images. From June 9 to June 12, 2003, the NOAA 10375, which has a \delta configuration, produced major flare activity. An X1.7 event occurred on June 9 with an associated Type II radio burst. On June 10, the region produced numerous M-class flares including an M5.6 flare at 18:15 UT. Two X-class flares occurred on June 11. On June 12, the region produced four M-class flares, including an M1.1 flare at 17:12 UT. We use speckle reconstructed data obtained with the new real-time image reconstruction (RTIR) system at BBSO that is a unique instrument for high-spatial resolution observation of the Sun. We also use high resolution H\alpha data taken at the 65 cm vacuum reflector to study chromospheric activity. In addition, we combine TRACE, MDI and RHESSI data to study the temporal evolution and connectivity of magnetic structures for a better understanding of active region evolution and the dynamics of the activity.
