Abstract
The gradients of line-of-sight magnetic fields in active region NOAA 6 659 on 1991 June 8 have been calculated based on the photospheric and chromospheric Magnetograms taken at Huairou Solar Observing Station. W e found that high gradients coincided with high strengths of the trans verse magnetic fields, implying a complicated configuration of the mag netic field in the lower atmosphere. For this extraordinarily flare-pr olific region, a possible relationship between the gradients and the f lares was inferred.
