Top: combined ATCA and TELAMON light curve with flare fits. Center: TELAMON fractional polarization at 20 mm and 7 mm. The inclined lines indicate the direction of the EVPA; errors are indicated by the shaded regions in EVPA and polarization. In addition to the TELAMON polarization values, we display the fractional polarization and EVPA of the VLBA data, for better visibility without uncertainties. Bottom: spectral index evolution obtained from TELAMON observations between 20 mm and 7 mm. The dashed red line indicates the time of IC220225A.
