Swift Observations of GRB 171010B

D.M. Palmer (LANL) and B. Sbarufatti (PSU) for the Swift team

1. Introduction

At 20:59:24.168 UT on 2017-10-10, the Swift Burst Alert Telescope (BAT) triggered on GRB 171010B (trigger=778019) (Palmer and Lien GCN Circ. 21995). However, on-board analysis was truncated by a pre-planned slew to a scheduled target. 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.

Standard analysis products for this burst are available at https://gcn.gsfc.nasa.gov/swift_gnd_ana.html.

BAT light curve

Figure 1. The BAT mask-weighted light curve in the four individual and total energy bands. The units are counts s-1 illuminated-detector-1. The vertical green dash-dotted lines show the T50 interval, the vertical black dashed lines show the T90 interval, and vertical blue (orange) solid lines show the start (stop) of slews.

XRT light curve
