We build the coincidence analysis method on the timing (and the possible sky position) of neutrino data from several detectors, together with gravitational wave data to make triggers of putative core collapse supernovae (like SN1987A). These putative triggers will be sent to astronomical electromagnetic wave observatories to be used as references to observe sky locations in some period of times to make the follow-up observations. The coincidence analysis among neutrino detectors as well as gravitational wave detectors will lower false alarm rate so that this method will increase the confidence level of a real core collapse event and its determination in time and sky position. This will lead to a higher probability to catch the first electromagnetic wave emission by astronomical observatories. To determine the triggers, we use two different approaches: one on a single-event basis and one on a statistical basis with binomial test.
