Transient magnetic field changes in flaresMagnetic changes have been detected with the videomagnetograph (VMG) at Big Bear during two large flares in 1979 November 5. Two kinds of changes were detected in both flares: a decrease in satellite field strength near the locus of the flare and the appearance of strong transient fields during the peak of the flare. We explain why we believe that the observed effects are real and not instrumental and discuss their significance for flare studies.
