TRIGGER_INDEX:   148
RATE_SIGNIF:     15.16 [sigma]

FLAGS:           0x1

SUN_DIST:         18.13 [deg]   Sun_angle= -1.2 [hr] (East of Sun)

GAL_COORDS:      162.92,-31.29 [deg] galactic lon,lat of the burst (or transient)
ECL_COORDS:       51.69,  2.12 [deg] ecliptic lon,lat of the burst (or transient)
COMMENTS:        SWIFT Figure-of-Merit decision.  
COMMENTS:        This was of sufficient merit to become the new Automated Target;  
COMMENTS:        but if the Current PPT has a greater merit, then we will not request a slew.  
COMMENTS:        This does not match any source in the ground catalog.  
COMMENTS:           
COMMENTS:        The next comments were copied from the BAT_POS Notice:  
COMMENTS:        This is a rate trigger.  
COMMENTS:        A point_source was found.  
COMMENTS:        This does not match any source in the on-board catalog.  
COMMENTS:        This is a GRB.  
COMMENTS:        Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.  
COMMENTS:        This trigger occurred at longitude,latitude = 93.12,4.10 [deg].
