GRB 191031D: XMM-Newton upper limit
Abstract
XMM-Newton started observing the field of the short GRB 191031D (Fermi-GBM et al., GCN Circ. 26111; D'Elia et al., GCN Circ. 26112; Mailyan et al., GCN Circ. 26118; Ursi et al., GCN Circ. 26123; Frederiks et al., GCN Circ. 26126; Gaikwad et al., GCN Circ. 26129; Frederiks et al., GCN Circ. 26149; Shimizu et al., GCN Circular. 26240) on 14 November 2019 at 09:58:00 UT, ~ 13.5 d after the burst. The last ~18 ks of the observation were affected by an enhanced background and were filtered out. The resulting EPIC/pn exposure time is 27.2 ks. No X-ray source is detected within the enhanced XRT position (Osborne et al., GCN Circ. 26117) down to a 3sigma limit of ~ 1.6e-3 cts/s in the 0.3-10 keV energy range. Assuming the spectral parameters derived by Swift/XRT, the above value translates into an unabsorbed flux limit of ~ 4.8e-15 erg/cm^2/s in the 0.3-10 keV energy range. We acknowledge the XMM-Newton staff for their support in scheduling and executing these observations.
