In her thesis Kasia demonstrated how a by product of LOFAR calibration, namely the ionospheric phase solutions in the direction of a bright calibrator, can provide valuable and unprecedented input to our understanding of small scale ionospheric processes. For the first time correlation of LOFAR ionospheric measurements with very small local magnetic field distortions was shown. This work strengthens the collaboration between ionospheric scientists an the low frequency radio astronomical community.
