An umbral flare in NOAA 6223 was observed at Huairou Solar Observing Station of Beijing Astronomical Observatory. Vigorous filament activity took place in association with this umbral flare. Several filaments formed and/or disappeared, leaving the magnetic neutral lines pointing to or rooted in the P spot in which the umbral flare occurred. We describe the observed configuration and evolution of the vector magnetic fields in the photosphere, and Doppler velocity patterns in the chromosphere during the course of the umbral flare and related filament activity.
