Comments: Beam time accounting according to halog entry 294302 (ABU even when Compton unusable). One minute BNA per trip. 17:00 Trip rate increases for one hour 19:10 Half hour of basically just trips 21:00 Much better conditions with B and C off 23:00 Good conditions even with B and C on 23:30 No beam because of MCC IOC reboot
