             abstract = "The confrontation of gravitational waves (GWs) with their 
                         electromagnetic (EM) counterparts will be rich with information 
                         about astrophysical events. Initially, this confrontation will 
                         corroborate GW detections; afterwards, when GW detections become 
                         more recurrent, it will allow astrophysics to combine information 
                         from different channels (GW, EM and also neutrinos). A low-latency 
                         data analysis which provides the direction of an incoming GW 
                         candidate is required to confront it with fast follow-up EM 
                         observations. Until now, no low-latency data analysis has been 
                         developed for spherical detectors. One spherical detector alone is 
                         capable of determining both the GW direction and polarization. By 
                         using this capability, we have developed a low-latency data 
                         analysis pipeline for the Mario Schenberg detector. This pipeline 
                         is able to retrieve the direction of GW triggers with an average 
                         angular resolution from \δs ~ 8° at SNR ~ 12 to \δs ~ 
                         1° at SNR ~ 80, in a timespan of a 4 s for 32 s of data being 
                         analyzed. We apply a veto which reduces fake events up to 90% when 
                         maintaining the GW efficiency above 90% for high SNRs. We provide 
                         here a description of the method and its efficiency: resolution on 
                         the direction, false alarm rate and computational time.",
