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 matches a source in the on-board catalog: Num=10767=(null) (probably an AT_Slot).  
COMMENTS:        This matches a source in the ground catalog: GRS1716n249,   delta=0.014 [deg].  
COMMENTS:        This is not a GRB.
