LOFAR S₄ of CasA (a, b) and CygA (c, d) calculated respectively for days 271 and 275 of 2017, recorded on LOFAR station PL612. ROT values calculated for 1 s (e, f) and 60 s (g, h) for days 271 and 275 of 2017. GNSS S₄ index observed on L1, L2 and L5 frequencies recorded with the ionospheric monitor collocated with the PL612 LOFAR station superimposed on CasA and CygA S₄ index calculated for the 48.92 MHz channel (i, j).
