A. Maselli (INAF-IASFPA), D. Malesani (DARK/NBI), K.L. Page and P.A.
Evans (U. Leicester) report on behalf of the Swift-XRT team:
Swift-XRT has conducted further observations of the field of the
Fermi-detected burst GRB 160422A (Yassine et al., GCN Circ. 19329; Burns
et al., GCN Circ. 19331), extending from T0+400 ks to T0+470 ks after
the Fermi/GBM trigger.
At the position of the candidate afterglow reported by Maselli et al.
(GCN Circ. 19334) no source is detected in the new observation, with a
three sigma upper limit of 2.6e-3 ct/s. This confirms that it was the
X-ray afterglow of GRB 160422A.
The results of the full analysis of the XRT observations are available
