GRB_TIME:        68788.56 SOD {19:06:28.56} UT
TRIGGER_INDEX:   155
RATE_SIGNIF:     24.53 [sigma]
IMAGE_SIGNIF:    6.53 [sigma]
FLAGS:           0x1
MERIT:           -400.00
SUN_POSTN:       197.91d {+13h 11m 39s}   -7.59d {-07d 35' 37"}
SUN_DIST:         66.09 [deg]   Sun_angle= -4.5 [hr] (East of Sun)
MOON_POSTN:      243.86d {+16h 15m 27s}  -17.00d {-16d 59' 46"}
MOON_DIST:        20.93 [deg]
MOON_ILLUM:      15 [%]
GAL_COORDS:       13.32,  9.89 [deg] galactic lon,lat of the burst (or transient)
ECL_COORDS:      264.77, 10.87 [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:        This trigger occurred during a high background rate interval.  
COMMENTS:        Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.  
COMMENTS:        This trigger occurred at longitude,latitude = 275.71,-14.64 [deg].
