COMMENTS: This is a GRB. COMMENTS: Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection. ////////////////////////////////////////////////////////////////////// TITLE: GCN/SWIFT NOTICE NOTICE_DATE: Sun 18 Sep 05 19:43:47 UT NOTICE_TYPE: Swift-XRT Position TRIGGER_NUM: 155764, Seg_Num: 0 GRB_RA: 75.2340d {+05h 00m 56.1s} (J2000), 75.2999d {+05h 01m 11.9s} (current), 74.6575d {+04h 58m 37.8s} (1950) GRB_DEC: -13.3654d {-13d 21' 55.4"} (J2000), -13.3573d {-13d 21' 26.3"} (current), -13.4377d {-13d 26' 15.7"} (1950) GRB_ERROR: 5.8 [arcsec radius, statistical plus systematic, 90% containment] GRB_INTEN: 175.88 [arb] GRB_SIGNIF: 4.58 [sigma] GRB_DATE: 13631 TJD; 261 DOY; 05/09/18 GRB_TIME: 70990.95 SOD {19:43:10.95} UT [Start of CCD integration] TAM[0-3]: 327.63 237.20 261.30 242.86 AMPLIFIER: 2 WAVEFORM: 134 SUN_POSTN: 176.31d {+11h 45m 16s} +1.60d {+01d 35' 45"} SUN_DIST: 101.08 [deg] MOON_POSTN: 5.73d {+00h 22m 56s} +1.73d {+01d 44' 05"} MOON_DIST: 70.58 [deg] MOON_ILLUM: 99 [%] GAL_COORDS: 212.93,-30.46 [deg] galactic lon,lat of the burst ECL_COORDS: 72.18,-35.90 [deg] ecliptic lon,lat of the burst COMMENTS: SWIFT-XRT Coordinates.
