Scientific paper

During the extremely active solar period from January 16th - 22nd, 2005, when several large X-class solar flares occurred, the MINIS (MINIature Spectrometer) balloon campaign had multiple payloads aloft in the stratosphere above Antarctica. Four MINIS balloons were launched from SANAE (South African National Antarctic Expedition) IV and measured DC electric fields, conductivity and x-ray flux. Increases in the conductivity and decreases in the vertical electric field magnitude were observed in conjunction with increases in particle flux seen by the balloon instruments as well as geospace satellites, reaffirming a direct connection between the solar activity and atmospheric electrodynamics. Additionally, a sustained (several hour) vertical field reversal was observed by one of the balloon instruments implying that a significant amount of positive charge was deposited below the balloon. This suggests that significant charge redistribution resulted from the solar flare and should be accounted for when describing the global electric circuit during active solar periods. By including rigidity cut-off estimates for the solar energetic particle (SEP) events based on ground based monitors we show that the reversal could have occurred over a significant portion of the globe.
