Exoplanetary science has been full of surprises, one is the discovery that planets can orbit their stars on highly misaligned (oblique) or even retrograde orbits. We have already shown that the obliquity of massive, close in planets (hot Jupiters) is shaped and reduced by tidal interactions. However, the origin of the large obliquities is not yet well understood. Obliquities can either be a signpost of planet migration, or are a result of misaligned protoplanetary disks connected to a potentially fundamental process during star formation. We can test the different theories by measuring obliquities for planets in wide orbits (warm Jupiters) as the different theories predict either alignment or misalignment. But transiting warm Jupiters are poorly studied objects. Here we propose to target a key multiplanetary system containing a warm Jupiter, EPIC 249624646. Its large transit duration means we cannot get the entire transit in a single night, but we propose to carry out these observations with the combination of the HDS and HARPS-N spectrographs, giving us adequate precision to help answering the science case. This is the first ever attempt to conduct sequential observations between Subaru/HDS and TNG/HARPS-N
