COMMENTS:        SWIFT-BAT GRB Coordinates.  
COMMENTS:        This Notice was delayed by more than 60 sec past the end of the trigger integration interval;  
COMMENTS:        probably due to it occurring during a Malindi downlink session.  
COMMENTS:        This is a rate trigger.  
COMMENTS:        A point_source was found.  
COMMENTS:        This is a low-flux event whose position matches one of the nearby galaxy sources in the on-board catalog!  
COMMENTS:        This matches a source in the on-board catalog: Num=12779=A0753-2802,   delta=0.196 [deg].  
COMMENTS:        This matches a source in the ground catalog: A0753-2802,   delta=0.196 [deg].  
COMMENTS:        This is a GRB in nearby galaxy or it is noise.  
COMMENTS:        This trigger occurred at longitude,latitude = 176.29,20.55 [deg].  
COMMENTS:        This AT will self-cancel at the end of the first orbit (ie I_signif<7.0 && Trig_dur<65msec).
