Abstract	This note summarizes the experimental results obtained during the 2018 LHC Machine Development program during the measurements campaign of the Beam-Beam Long-Range compensation using DC wires (MD3263). After the promising results obtained with the prototypes installed in IR5 in 2017, two new ones have been installed in IR1 during the EYETS 2017-18. They were commissioned with beam during the two first blocks of 2018 MDs (MD#1 and MD#2). More complex configurations were tested in the second part of the year: (i) compensation while reducing the crossing angle (MD#3) and (ii) compensation with trains in a configuration compatible with operation (MD#4).
