K.L. Page (U. Leicester), J. L. Racusin (NASA/GSFC), J.A. Kennea (PSU) and
J.K. Cannizzo (NASA/UMBC) report on behalf of the Swift-XRT team:
Following a Target of Opportunity request, Swift started observing the
field of the Fermi GBM- and LAT-detected GRB 100414A about 48 hours after
the trigger (GCN Circs. 10594, 10595). In 1.4 ks of data there is an
uncatalogued source detected within the XRT field of view, at a position
of RA, Dec = 192.11199, 8.69172, which is equivalent to
RA (J2000): 12 48 26.88
Dec (J2000): +08 41 30.2
with an uncertainty of 3.8 arcsec (radius, 90% containment).
The source is at a count rate of 0.022 +/- 0.004 count s^-1 (0.3-10 keV),
corresponding to an observed flux of ~1.31x10^-12 erg cm^-2 s^-1; however,
with the limited data collected so far, it is not possible to determine
whether this source is fading.
