L.M. McCauley (PSU) and F.E. Marshall (NASA/GSFC) for the Swift team
Mereghetti et al. (GCN Circ. 20021) reported the GRB detection. A gamma ray burst lasting about 30 s has been detected by IBAS in the IBIS/ISGRI data at 13:36:32 UT of 2016 October 10. Table 1 contains the best reported positions from Swift.
Marshall and D'Ai (GCN Circ. 20034) 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
(Marshall and D'Ai GCN Circ. 20034) of the field of GRB 161010A 3.3 hours after the INTEGRAL trigger (Mereghetti et al., GCN Circ. 20021).
A source consistent with the XRT position (McCauley et al., GCN Circ. 20025) is detected in the initial UVOT exposures.
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.

Any data from a crosshatched region are not included in the fit.
