Due to the lack of onboard image detection, Swift did not slew to the GRB and so there were no immediate XRT or UVOT follow-up observations. Swift has initiated a ToO observation.
XRT: One uncatalogued X-ray source has been detected, but at the present time we cannot confirm this as the afterglow.
UVOT: no detection
