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 an image trigger.  (The RATE_SIGNIF & BKG_{INTEN, TIME, DUR} are undefined.)  
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=12354=NGC7462,   delta=0.118 [deg].  
COMMENTS:        This matches a source in the ground catalog: NGC7462,   delta=0.118 [deg].  
COMMENTS:        This is a GRB in nearby galaxy or it is noise.
