The collapse of the core of a star is expected to produce gravitationalradiation. While this process will usually produce a luminous supernova, theoptical signatue could be subluminous and a direct collapse to a black hole,with the star just disappearing, is possible. The gravitational wave eventGW150914 reported by the LIGO Virgo Collaboration (LVC) on 2015 September 16,was detected by a burst analysis and whose high probability spatiallocalization included the Large Magellanic Cloud. Shortly after theannouncement of the event, we used the Dark Energy Camera to observe 102deg$^2$ of the localization area, including a 38 deg$^2$ area centered on theLMC. Using a catalog of 152 LMC luminous red supergiants, candidates to undergoa core collapse without a visible supernova, we find that the positions of 144of these are inside our images, and that all are detected - none havedisappeared. There are other classes of candidates: we searched existingcatalogs of red supergiants, yellow supergiants, Wolf-Rayet stars, and luminousblue variable stars, recovering all that were inside the imaging area. Based onour observations, we conclude that it is unlikely that GW150914 was caused bythe core collapse of a supergiant in the LMC, consistent with the LIGOCollaboration analyses of the gravitational wave form as best described by abinary black hole merger. We discuss how to generalize this search for futurevery nearby core collapse candidates.
