英文摘要	We present observations of the violent changes in photospheric magnetic structures associated with an X1.1 flare, which occurred in a compact delta-configuration region in the following part of AR 11890 on 2013 November 8. In both central and peripheral penumbra regions of the small delta sunspot, these changes took place abruptly and permanently in the reverse direction during the flare: the inner/outer penumbra darkened/disappeared, where the magnetic fields became more horizontal/vertical. Particularly, the Lorentz force (LF) changes in the central/peripheral region had a downward/upward and inward direction, meaning that the local pressure from the upper atmosphere was enhanced/released. It indicates that the LF changes might be responsible for the penumbra changes. These observations can be well explained as the photospheric response to the coronal field reconstruction within the framework of the magnetic implosion theory and the back reaction model of flares.
