IBIS-ISGRI observations on 2010-10-10 (Bordas et al. ATel #2919) as well as RXTE-PCA scans on 2010-10-09 (http://lheawww.gsfc.nasa.gov/users/craigm/galscan/html/EXO_1745-248.html) showed enhanced X-ray emission from the direction of the globular cluster Terzan 5. We analysed a ~500 s Swift-XRT observation of the field starting on 2010-10-10 01:32:05 UT, detecting one bright source at a position of RA=267.021 DEC=-24.781 (J2000; 3.6 arc-seconds error radius), consistent with Terzan 5 and about 5.3 arc-seconds from the Chandra location of the neutron star transient EXO 1745-248 (Heinke et al.
