E. Ambrosi (INAF-IASFPA) for the Swift team
Iwakiri et al. (GCN Circ. 25456) reported the GRB detection. The MAXI/GSC nova alert system triggered a bright uncatalogued X-ray transient source at 13:30:22 UT on 2019 August 23. Table 1 contains the best reported positions from Swift.
Table 2 is a summary of GCN Circulars about this GRB from observatories other than Swift.
BAT did not observe this burst.
Analysis of the initial XRT data was reported by D'Elia et al. (GCN Circ. 25680). The source previously reported by Ambrosi et al. (GCN Circ. 25476) is fading with 3-sigma significance, and is therefore likely the GRB afterglow. The source is fading with α >0.7.
UVOT results are not available.
