TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5600 SUBJECT: GRB 060923C, Swift-BAT partial refined analysis DATE: 06/09/23 22:42:57 GMT FROM: Scott Barthelmy at NASA/GSFC S. D. Barthelmy (GSFC), L. Barbier (GSFC), J. Cummings (GSFC/UMBC), E. Fenimore (LANL), N. Gehrels (GSFC), D. Hullinger (BYU-Idaho), H. Krimm (GSFC/USRA), C. Markwardt (GSFC/UMD), D. Palmer (LANL), A. Parsons (GSFC), T. Sakamoto (GSFC/ORAU), G. Sato (GSFC/ISAS), M. Stamatikos (GSFC/ORAU), J. Tueller (GSFC) on behalf of the Swift-BAT team: Using a partial data set from T-119 to T+183 sec from recent telemetry downlinks, we report further analysis of BAT GRB 060923C (trigger #230711) (Stamatikos, et al., GCN Circ. 5591). The BAT ground-calculated position is RA,Dec = 346.123, 3.963 deg {23h 4m 29.4s, 3d 57' 47.4"} (J2000) +- 2.2 arcmin, (radius, sys+stat, 90% containment). The partial coding was 17%. With only a partial data set downlinked (there is a gap in the data between T+51 to +62 sec), the mask-weighted lightcurve has a single long emision from T+0 to T+110 sec. The lower limit to the fluence in the 15-150 keV band is 1.3 +- 0.2 x 10^-6 erg/cm2. We repeat that there is an 11-sec gap in the data in the middle of this burst used for this analysis. When the full data set is downlinked, we will report the usual numbers.
