LHCb has recently published measurements of $J/\psi$ and open charm production cross-sections using data taken at a proton-proton centre-of-mass energy of 13 TeV. The measurements at this new energy not only provide further tests of QCD predictions, but can also be used to constrain parton distribution functions and to estimate charm backgrounds in cosmic neutrino experiments such as IceCube. In this Collider Cross Talk, the two new measurements will be presented and discussed, along with an overview of the real-time calibration and alignment procedure that allowed for a very short time between data-taking and publication.
