The LMJ*, a 176-beam laser facility developed by the French Nuclear Science directorate CEA, is located at the CEA** CESTA site near Bordeaux. The LMJ facility is part of the French Simulation Program. It is designed to deliver about 1.4 MJ of energy on targets, for high energy density physics experiments, including fusion experiments. Since 2022, the LMJ facility aims at carrying out experiments with 12 bundles of 8 laser beams and 12 target diagnostics. In order to achieve daily shots including all the preparatory steps, the LMJ performs night activities from now on and the presence of technical operators is not required. These sequences work on vacuum windows inspection and beam alignment. They take into account all the prerequisites for their good performances and are scheduled automatically one after the other. They deal with material security and unexpected equipment alarms. They endeavour to required tasks success and give a detailed report of the night events to the shot director. This paper gives a presentation of the two sequences with solutions in order to answer the technical specifications and the last enhancements.
