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 matches a source in the on-board catalog: Num=23792=(null) (probably an AT_Slot).  
COMMENTS:        This matches a source in the ground catalog: XTE J1752-223,   delta=0.024 [deg].  
COMMENTS:        This is not a GRB.  
COMMENTS:        This is an interesting source.
