             abstract = "The development and optimization of technologies has proved of 
                         extreme value for studies of the solar magnetic field through 
                         solar observations in Earth. An example is the increase quality of 
                         the images obtained by telescopes due to the improvement of the 
                         spatial resolution. Cooperatively with the development of 
                         technologies, the use of techniques such as spectropolarimetry 
                         makes it possible to characterize fine structures and obtain 
                         characteristics of the solar magnetic field. However even with all 
                         the progress, there is still no complete understanding of the 
                         physical processes that lead to the solar activity cyclic 
                         variability and its long-term changes, making detailed studies of 
                         the solar magnetic field more fascinating. A spectropolarimeter 
                         was developed containing sCMOS Cameras, 500mm Aperture Commercial 
                         Telescope, Polarization Kit, Fary-Perot Etalon interferometer, 
                         narrow band filters and all customized optics. In the present 
                         work, we show the preliminary results of observation cycles being 
                         performed, with images captured for more than one hundred 
                         wavelengths (positions in the interferometer) and in 8 states of 
                         polarization. The instrument allows to make observations at 
                         different wavelengths (within an emission band) and with different 
                         polarizations, in order to obtain the estimates of the 
                         distribution of the magnetic field vector in the solar disk 
                         images, providing important data to better understanding the Suns 
                         influence on the Geospace and on Earths Climate.",
