TRIGGER_INDEX:   20000
RATE_SIGNIF:     0.00 [sigma]
IMAGE_SIGNIF:    6.99 [sigma]
FLAGS:           0x3

SUN_DIST:         64.46 [deg]   Sun_angle= 4.4 [hr] (West of Sun)
MOON_POSTN:        0.02d {+00h 00m 04s}   +1.10d {+01d 05' 59"}
MOON_DIST:        92.79 [deg]
MOON_ILLUM:      6 [%]
GAL_COORDS:        7.72,  3.79 [deg] galactic lon,lat of the burst (or transient)
ECL_COORDS:      267.40,  3.04 [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: H1745-203,   delta=0.012 [deg].  
COMMENTS:           
COMMENTS:        The next comments were copied from the BAT_POS Notice:  
COMMENTS:        This is an image trigger.  (The RATE_SIGNIF is undefined.)  
COMMENTS:        A point_source was found.  
COMMENTS:        This matches a source in the on-board catalog.  
COMMENTS:        This is not a GRB.  
COMMENTS:        Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.  
COMMENTS:        This trigger occurred at longitude,latitude = 190.91,16.68 [deg].
