77 years after its previous outburst, and with a recurring time of 80 years, the symbiotic recurrent nova (RN) T CrB is expected to go into outburst very soon, as also anticipated by its current "super active phase" (SAP). RNe are rare systems, and potential progenitors of type 1a supernovae. The outburst causes shocks in the ISM, leading to the emission of (very) high energy gamma rays and rapidly evolving and long lived radio outflows. At a distance of 0.9 kpc, T CrB is the closest of RNe and its outburst will be bright enough to easily detect across all wavebands and be a once-in-a-generation chance to study this source. As part of a multi-instrument preparation for the upcoming event, we propose to observe the source during the current SAP and pre-outburst with the EVN and e-MERLIN at 1.6 and 5 GHz. This will serve to facilitate the calibration and the interpretation of the data from the outburst, which we will request with a dedicated ToO OoS proposal (as for the RS Oph 2021 event).
