Monitoring the evolution of the compact emission of Arp220


We request global VLBI observations of the compact continuum emission of Arp220 at L-band (2 epochs) and individual epochs at C- and X-band. The data will be used to accurately determine the light curves and spectra of the radio supernovae and therefore to study their evolution.
