The BRICS Astronomy Working Group Meeting 2023 was hosted by South Africa at SAAO‘s headquarters in Cape Town. The meeting ended on a high note with a Data Science Hackathon organized by Hack4dev and by the indefatigable Eslam Hussein in particular. Well done to the 30 participants and to the tutors who showed them the ways of data science applications in astronomy in a friendly and collaborative context. Per Astra ad Aspera;-)
