TITLE: GCN CIRCULAR
NUMBER: 14964
SUBJECT: GRB 130623A: Second Swift-XRT observation

Dirk Grupe (PSU) reports on behalf of the Swift team:
Swift reobserved the field of the ground-detected GRB 130623A
(Cummings, GCN circ. 14921) again on 2013-June-30 for 10.25 ks.
The source reported initially in Grupe et al. (circular 14926)
seems to have faded. We do not detect the source anymore and
can only measure a 3 sigma upper limit at a level of
1.9e-3 counts/s in the XRT.
This measurement suggests that the source reported in
Grupe et al. (circular 14926) is may be the X-ray
afterglow of GRB 130623A.
The results of the XRT-team automatic analysis are available at
http://www.swift.ac.uk/xrt_products/00020284.
This circular is an official product of the Swift XRT team.
