report on behalf of the Swift-XRT team:
The XRT began observing the field of GRB 140621A on 2014-06-23 at
21:01:54 UT, 177 ks after the IPN trigger (Golenetskii et al. GCN Circ
16444, 16445; Younes & Meegan, GCN Circ 16447). An observation
centered on RA, Dec: 25.0642, 22.4111 has been secured.
In the 4 ks exposure covering 60% of the IPN box that remained after
the BAT non-detection exclusion, we do not find any new X-ray source,
down to a three sigma upper limit of 3.05E-03 cts/s.
