Finally the first work-visit after the pandemic unleashed! Our friends from the Instituto de Astrofísica de Canarias, Sergio Simón Díaz and Abel de Burgos, visited CAB in June. We discussed recent advances of the IACOB database and tools, progress on metal-poor massive stars, machine learning applied to massive stars, shortcomings of the state-of-the-art codes FASTWIND and CMFGEN, and the possible expansions of the grid of FASTWIND models managed by the broad Spanish team of massive stars. Very productive days, and hopefully the first of many to come.
