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=10361=4U 1850-087,   delta=0.031 [deg].  
COMMENTS:        This matches a source in the ground catalog: 4U 1850-087,   delta=0.031 [deg].  
COMMENTS:        This is not a GRB.  
COMMENTS:        This is an interesting source.
