Keck images of the region surrounding OGLE-2016-BLG-1195 from OSIRIS 2020 (left) and NIRC2 2018 (right). In each case the position of the microlensed source (in the 2016 bulge frame) is superposed as a blue circle. The pixel sizes are, respectively, 10 and 40 mas. North is up and east is left. Vandorou et al. (2023) identified the southeast star (or asterism) as the location of the microlensing event, whereas our analysis suggests that this is more likely to be the northwest star.
