A. D'Aì (INAF-IASFPA) and L.M.Z. Hagen (PSU) for the Swift team
Racusin and Kocevski (GCN Circ. 19902) reported the GRB detection. At 17:19:39 on September 10, 2016 Fermi-LAT detected high-energy emission from GRB 160910A, which was also detected by Fermi-GBM (trigger 495220782/160910722; Veres et al. GCN Circ. 19901). Table 1 contains the best reported positions from Swift.
Malesani et al. (GCN Circ. 19908) reported the position from NOT for the optical afterglow of this GRB. Hagen and Cummings (GCN Circ. 19923) reported the detection with UVOT of an optical afterglow. Table 2 is a summary of GCN Circulars about this GRB from observatories other than Swift.
BAT did not observe this burst.
XRT refined results are not available.
The Swift/UVOT began settled observations
(Hagen and Cummings GCN Circ. 19923) of the field of GRB 160910A 196954 s after the Fermi/GBM (Veres et al., GCN Circ. 19901) and Fermi/LAT (Racusin et al., GCN Circ. 19902) triggers.
We detect a fading source consistent with the XRT position (D'Ai et al., GCN Circ. 19904) and optical detections (de Ugarte Postigo et al., GCN Circ. 19907; Malesani et al., GCN Circ. 19908; Lipunov et al., GCN Circ. 19914; Mazaeva et al., GCN Circ. 19919).
Table 3 gives preliminary
magnitudes using the UVOT photometric system
(Breeveld et al. 2011, AIP Conf. Proc., 1358, 373).
No correction has been made for the expected extinction in the Milky Way
corresponding to a reddening of
Figure 1. The BAT light curve is not available.
