Small Scale Magnetic Field Mapping with High Temporal Resolution
Abstract
Two dimensional maps of the longitudinal magnetic field can be readily calculated for small-scale magnetic regions. Here we use a one hour time sequence of high spatial resolution (0.75 arc sec) filtergrams, obtained at the Sacramento Peak Vacuum Tower Telescope with the universal filter (UBF) in the wings of the magnetically sensitive lambda 6103 CaI line. The time difference between two magnetic maps is 32 sec. The measurements of the magnetic field in the blue wing are about 40% higher than in the red wing.
