TRIGGER_INDEX:   155
RATE_SIGNIF:     9.94 [sigma]
IMAGE_SIGNIF:    6.55 [sigma]
FLAGS:           0x3
MERIT:           100.00
SUN_POSTN:       227.27d {+15h 09m 05s}  -17.66d {-17d 39' 48"}
SUN_DIST:         51.63 [deg]   Sun_angle= 2.6 [hr] (West of Sun)
MOON_POSTN:      236.53d {+15h 46m 07s}  -15.50d {-15d 30' 14"}
MOON_DIST:        57.62 [deg]
MOON_ILLUM:      1 [%]
GAL_COORDS:      277.82, 78.48 [deg] galactic lon,lat of the burst (or transient)
ECL_COORDS:      180.32, 18.30 [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:        FOM will request the s/c to slew.  
COMMENTS:        The S/C has yet to make its decision about safe to slew or not.  
COMMENTS:        This matches a source in the ground catalog: NGC4489,   delta=0.161 [deg].  
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 matches a source in the on-board catalog.  
COMMENTS:        This is not 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 = 262.19,-14.60 [deg].
