Abstract: 
New observational data obtained with spectral-polarized method are briefly presented. The data confirm the conclusion made earlier by the author that extremely strong magnetic fields may exist in solar flares which reach values of several tesla (-10 kG) in the upper photosphere and temperature minimum zone.
Keywords: solar flares, strong magnetic fields, upper photosphere
