At 10:50:38 UTC, Swift-BAT triggered on GRB 130418A (trigger # 556105). A
sub-threshold source was found onboard. In ground analysis, a source was
confirmed at RA, Dec 321.555, -20.148, which is:
RA (J2000) 21h 26m 13.2s

with an estimated uncertainty of 1.8 arcmin radius (90% confidence).
The burst as seen in BAT was a single FRED peak of approximately 15 seconds

A Swift TOO request has been submitted and approved to locate the afterglow.
