Friday 07:00 Fill 1729 dumped. Movement device allowed flag switching to FALSE. From the logs, it seems the energy went to FFFF/7860 GeV. To be confirmed by more a detailed analysis. 11:30 Fill 1730 in stable beams with 336 b / 72 b per injection. Initial luminosity ~3E32 cm-2s-1. Rather smooth. 16:10: Beam dumped. PC fault on RSD2.A67B1. 4.3 pb-1 in 4 ½ hours for fill 1730. 19:10: 1731 in stable beams with 480 b / 36 b per injection. Slightly higher current and luminosity: 33 MJ/beam. 4/25/2019 LHC 8:30 meeting

07:40 dump. Integrated lumi 15 pb-1 (new LHC record). Bunches in the last trains suffer more during collisions than the ones in the first trains. Integrated lumi > 100 pb-1 in 2011. 4/25/2019 LHC 8:30 meeting

Today Physics with 480b / 36b per injection. Fill lengths of 10 hours or so – avoid when possible fill/ramp/squeeze at transition of shifts. 4/25/2019 LHC 8:30 meeting
