QUBIC is making progress on the calibration source, which will be installed in the tower in Alto Chorrillos in the coming days. A significant group of QUBIC Collaboration members are currently in Salta to complete this task with part of the staff of QUBIC in that city. The photo shows, from left to right, Hernán Ocampo and Alejandro Soliz (Argentina), Youssef Moulane (Morocco), Mattia Bianchessi (Italy), Aoife Flood and Sabrina Marwerde (Ireland) and Fabricio Rodíguez (at the bottom, Argentina). Weather permitting, they will be traveling up to Alto Chorrillos next week..
